Description

Database-driven mind map production, display, splitting, grafting methods

technical field

The invention relates to the field of computers, in particular to a method for making, displaying, splitting and grafting a database-driven mind map.

Background technique

Mind maps are also known as brain maps, mind maps, brainstorming maps, brainstorming maps, concept maps, tree maps, branch maps or mind maps. The mind map structure includes a central theme and many subordinate themes radiating around the central theme. Using the technique of equal emphasis on pictures and texts, the relationship between the themes at all levels is expressed in a hierarchical diagram of mutual subordination and correlation, so that the themes at all levels can be related to images, images and texts. It is a tool for image-based thinking and an auxiliary tool for image-based thinking. It has the powerful function of human thinking and is an effective graphic thinking tool for expressing divergent thinking using graphics. Very effective, a practical thinking tool.

At present, the use of mind maps is becoming more and more extensive. It is widely used in system module and architecture design, test case division and production, etc., which can effectively improve the efficiency of collaboration.

There are two main ways to draw mind maps: manual drawing and software drawing.

To draw a mind map by hand, the basic method is: first plan a mind map design plan, conceive the style, color, and frame structure, then draw a central theme on a blank sheet of paper, manually draw nodes around the central theme, and draw a level 1 theme, Picture, connect the central theme and level 1 theme with connecting lines, manually draw nodes around the level 1 theme, draw level 2 themes and pictures, connect the level 1 theme and level 2 theme with connecting lines, and manually draw nodes around the level 2 theme , draw 3-level themes and pictures, connect the 2-level themes and 3-level themes with connecting lines, until all themes, connecting lines, and pictures are drawn, and the mind map is manually drawn.

Mainstream mind mapping tools include Mjndmanager, Xmjnd, WPS, Baidu Brain Map, MjndMaster, ProcessOn, Wancai, etc. The basic method of drawing mind maps with these software is: first plan the mind map design, then create a new mind map file, enter the drawing interface, set the style, color, frame structure, establish the central theme, manually add nodes around the central theme, insert For a level 1 theme, manually add nodes around a level 1 theme, insert a level 2 theme, manually add nodes around a level 2 theme, and insert a level 3 theme until the basic framework is built. When inserting themes at all levels, or after the framework is completed, add content, pictures, labels, etc. to each theme to complete the drawing of the mind map management software.

To draw a mind map by hand, the themes, connecting lines, pictures, etc. are all done by hand, which is time-consuming and labor-intensive. The software draws mind maps, style, color, frame structure, connecting lines, etc. The software has been designed, and pictures are saved on the computer. You can select and add manually. You only need to manually input the theme, so it is much easier and more efficient than manual drawing. , so it is more and more popular.

Application No. 201810843673.1 discloses a method for generating a mind map, receiving a text note to generate a mind map framework, automatically acquiring corresponding pictures, without manual hand-painting of images, reducing the time required for drawing images, thereby reducing the time spent in sorting out knowledge. Time required, application No. 201811148658.1 discloses a mind map display method and device, which can hide part of the content of the mind map, so that only the node content that the user wants to view is displayed in the display interface, so as to prevent the user from being affected by the content of other nodes. Influence, to solve the technical problem in the prior art that users are affected by the content of other nodes when viewing the partial content of the mind map. It can organically mine the potential relationship between user-marked information such as ideas published by readers, book reviews, and underlined content, so as to integrate and form an overview and framed mind map that reflects the user's overall cognition of the book.

Despite this, software production of mind maps still requires a lot of manual participation, and it is necessary to repeatedly insert nodes, themes, connecting lines, planning dimensions, locations, etc., and the efficiency is still not high enough, especially when mind maps are constructed and used in isolation. Database management, thus forming a mind map island, theme information cannot be shared between mind maps, and the value of mind maps is difficult to maximize.

The picture address can also be automatically imported, and the automatic picture matching switch is turned on. The mind map management software searches and reads the picture name, picture content, picture path and other attributes in the system, and automatically matches the pictures related to the theme content. Write the relative address string of the picture to the picture address.

The mind map graphic is automatically produced, the creator opens the mind map, selects a mind map, and obtains relevant parameters such as mind map coding, production time, completion time, etc. If the production time is not empty and the completion time is empty, Then the mind map graphic production is not completed, and the mind map management software queries all the subject content, font, font size and other parameters of the mind map from the subject table. According to the above parameters, the mind map management software draws the canvas and automatically calculates The coordinates of the starting point and the ending point of the theme, place the theme content and pictures on the main display area of the canvas, connect the parent theme and sub-theme with connecting lines, and generate a mind map of PC version, tablet version, and mobile version in the main display area of the canvas , the creator and creator manually fine-tune parameters such as frame structure and connection line type, move the theme content, picture placement, fine-tune font, font size, color, picture, theme position and other parameters, and save the adjusted parameters in the mind map, theme In the table, the mind map is completed, and the methods and steps are as follows:

Step S201, write the default value into the mind map table and the theme table:

The mind map management software opens the default value table, reads the width of the text box, the text margin in the text box, the taper ratio of the connecting line, the frame code of the PC version, the canvas width of the PC version, the canvas height of the PC version, and the width of the main display area of the PC version. , PC version main display area height, PC version level inner distance, PC version level spacing, tablet version frame code, tablet version canvas width, tablet version canvas height, tablet version main display area width, tablet version main display area height, tablet version The default settings are: level inner distance, tablet level distance, mobile version frame code, mobile version canvas width, mobile version canvas height, mobile version main display area width, mobile version main display area height, mobile version internal distance, mobile version level spacing, etc. value, and assign these default values to the mind map, write the mind map table, and the mind map management software reads the theme text color, text box color, connecting line color, PC version font, PC version font size, PC version connecting line Coding, PC version connecting line width, PC version text arrangement direction, tablet version font, tablet version font size, tablet version connecting line code, tablet version connecting line width, tablet version text arrangement direction, mobile version font, mobile version font size, mobile version Default values such as connection line code, width of the connection line, and orientation of the text, and assign these default values to the theme and write them into the theme table.

Step S202, draw the PC version canvas:

The mind map management software draws the canvas of the PC version according to the width of the canvas of the PC version, the height of the canvas of the PC version, the width of the main display area of the PC version, and the height of the main display area of the PC version. The origin (0,0) is the center of the field, the left part of the middle horizontal line is the -X axis, the right part of the middle horizontal line is the +X axis, the upper part of the middle vertical line is the +Y axis, and the lower part of the middle vertical line is -Y axis.

Step S203, calculate the length and height of the central theme of the PC version:

The central theme length LT0 is determined by the central theme word count, font, font size, text box border width, and padding, and the central theme height HT0 is determined by the central theme font, font size, text box border width, and padding.

Step S204, calculate the PC version theme length, height, level inner distance, and level distance:

All topics at the same level have the same length and height, and the minimum spacing between adjacent subtopics in the horizontal direction and the vertical direction are the same;

The length of the j-th topic LTj, j=1, 2, ... is determined by the word count, font, font size, text box border width, and inner margin of the topic with the largest number of words in the j-th topic;

The height of the j-th level theme HTj, j=1, 2, ... is determined by the word count, font, font size, text box border width, and padding of the theme with the largest number of words in the j-th level theme;

The level spacing C is the minimum vertical distance between adjacent topics at different levels. The level spacing of all levels is equal, which is equal to several multiples of the height of the central topic, generally equal to 4 times the height of the central topic, namely: C=4M*HT0, M> 0;

The intra-level distance R is the minimum vertical distance between adjacent topics in the same level. The distance between topics in the same level is equal, which is equal to several multiples of the height of the central topic, generally equal to 1 times the height of the central topic, that is: R= M*HT0, M>0.

Step S205, compare the width and height of the main display area and the mind map, automatically calculate and adjust the width and height of the main display area, the theme font size of the PC version, the level inside distance, and the level distance until they are suitable, and write the result into the mind map chart.

The mind map management software calculates the mind map length L, which is the sum of the lengths of all topics plus the level spacing:

L=LT0+C+LT1+C+LT2+……,j=1,2,3,……;

The mind map management software calculates the height H of the mind map, which is the sum of the heights of all topics in the level where the highest serial number is located in the level plus the distance between levels:

H=HT1+R+HT2+R+…, k=1, 2, 3,…;

If the height of the main display area>1.2*height of the mind map, it means that the main display area is too high and the height of the mind map is too low, then increase the level inner distance by 1 pixel each time, and repeat the calculation steps of step S203, step S204, step S205, Before the level inner distance reaches the maximum level inner distance of the PC version, if it reaches 1.1*mind map height < main display area height <1.2*mind map height, then stop increasing the level inner distance, adjust the level inner distance in place, and in the level inner distance When the maximum inner distance of the PC version is reached, there is still the height of the main display area>1.2*the height of the mind map, then increase the font size by 1 pixel each time, and repeat the calculation steps of steps S203, S204, and S205, until the font size reaches the maximum of the PC version. Before the font size, if it reaches 1.1* mind map height < main display area height < 1.2* mind map height, then stop increasing the font size, and adjust the font size in place. When the font size reaches the maximum font size of the PC version, the height of the main display area is still >1.2* The height of the mind map indicates that the height of the main display area is too high, then reduce the height of the main display area until 1.1*mind map height < height of the main display area<1.2*mind map height, the height of the main display area, the inter-level distance, The font size is adjusted.

If the height of the main display area is less than 1.1*height of the mind map, it means that the main display area is too low and the height of the mind map is too high, then reduce the inner distance by 1 pixel each time, and repeat the calculation steps of steps S203, S204, and S205, Before the level inner distance reaches the minimum level inner distance of the PC version, if it reaches 1.1*mind map height < main display area height <1.2*mind map height, stop reducing the level inner distance, adjust the level inner distance in place, and in the level inner distance When the minimum level inner distance of the PC version is reached, the height of the main display area is still less than 1.1* the height of the mind map, then the font size is reduced by 1 pixel each time, and the calculation steps of steps S203, S204, and S205 are repeated, and the font size reaches the minimum of the PC version. Before the font size, if it reaches 1.1* mind map height < main display area height < 1.2* mind map height, stop reducing the font size, and adjust the font size in place. When the font size reaches the minimum font size of the PC version, the height of the main display area is still <1.1* The height of the mind map, stop reducing the font size, and adjust the height of the main display area, the inner spacing, and the font size.

The mind map management software calculates the length Lk of the subject keyword with the largest number of words according to the adjusted font size, Lk = subject keyword length (max (the number of words of the j-th subject keyword), font, font size, text box width, text edge distance), j=1, 2, 3, ….

If the length of the main display area is greater than 1.2* the length of the mind map, it indicates that the main display area is too wide and the length of the mind map is too low, then increase the level spacing by 1 pixel each time, and repeat the calculation steps of steps S203, S204, and S205, and in Before the level spacing reaches the maximum level spacing of the PC version, if it reaches 1.1*mind map length<main display area length<1.2*mind map length, stop increasing the level spacing, adjust the level spacing in place, and reach the maximum level spacing of the PC version when the level spacing reaches the maximum level spacing of the PC version. When there is still the length of the main display area>1.2*mind map length, it means that the length of the main display area is too long, then reduce the length of the main display area until 1.1*mind map length<main display area length<1.2*mind map length, the length of the main display area, and the interval between stages have been adjusted.

If the length of the main display area is less than 1.1* the length of the mind map, it indicates that the main display area is too narrow and the length of the mind map is too wide, then reduce the level spacing by 1 pixel each time, and repeat the calculation steps of steps S203, S204, and S205. Before the level spacing reaches the minimum level spacing of the PC version, if it reaches 1.1*mind map length < main display area length<1.2*mind map length, stop reducing the level spacing, adjust the level spacing in place, and reach the minimum level spacing of the PC version when the level spacing reaches the minimum level spacing of the PC version When there is still the length of the main display area < 1.1* the length of the mind map, the pixel width of the theme text box is reduced by 1 character each time, and the calculation steps of step S203, step S204, and step S205 are repeated, and the calculation steps of step S203, step S204, and step S205 are repeated. Before the length reaches 1.1*mind map length < main display area length<1.2*mind map length, stop reducing the length of the subject text box, stop adjusting the subject length, and adjust the subject length in place, if the subject length <= subject keyword length After that, the length of the main display area is still less than 1.1* the length of the mind map, stop adjusting the theme length, and the length of the main display area and the level spacing are adjusted.

Step S206, calculate the central theme of the left and right structure of the PC version and the coordinates of the starting point, end point, and sub-connection point of the picture, and use the set font, font size, color, arrangement direction, etc., to display the central theme and the picture in the corresponding position, and the results Write to the subject table:

The origin of the left and right structures (0,0) is at the midpoint of the left line of the field grid, the midpoint of the left side of the central theme text box is coincident with the origin (0,0), the theme centerline of the central theme coincides with the X axis, and the theme text head is up , arranged horizontally from left to right and left.

The relevant coordinate values of the central topic T0 are as follows:

The abscissa of the starting point of the central theme = 0;

The ordinate of the starting point of the central theme = - the height of the central theme/2 = -HT0/2;

The abscissa of the end point of the center topic = the length of the center topic = LT0;

The ordinate of the end point of the central theme = the height of the central theme/2= HT0/2;

The abscissa of the central theme sub-connection point = the length of the central theme = LT0;

center topic sub-connection point ordinate = 0;

The central theme picture is left-aligned with the central theme, and is vertically separated from the central theme by a distance R. The calculation method of the relevant coordinate value of the picture is as follows:

The abscissa of the starting point of the central theme image = 0;

The vertical coordinate of the starting point of the central theme image = the height of the central theme/2+R= HT0/2+R;

The abscissa of the end point of the central theme image = the width of the PC version image;

The vertical coordinate of the end point of the central theme image = the height of the PC version of the image.

Step S207: Calculate the starting point coordinates, end point coordinates, parent connection point coordinates, child connection point coordinates, picture start point coordinates, and picture end point coordinates of the first-level median theme of the left and right structure of the PC version, and use the set font, font size, color, and arrangement direction. Etc., display the subject and picture in the corresponding position, iteratively calculate the relevant coordinates of all the 1st-level subjects with the median subject-related coordinates, subject length, and level distance, and write the results into the subject table:

Left-right structure The first-level topics are arranged on the right side of the central topic. The center lines of all topics in the first-level are parallel to the X-axis. The topic text heads up, from left to right, and horizontally to the left, extending to the +X-axis direction, horizontally. On the top, the header of the first-level topic and the tail of the central topic are separated by the PC version level distance C. In the vertical direction, the adjacent topics in the hierarchy are separated by the PC version level distance R. When the total number of the first-level topics t1 is an odd number, there are A median subject T1m, m=rounding(t1/2)=round(t1/2), the median line of T1m subject coincides with the center subject line, and when the total number of first-level subjects t1 is an even number, there are 2 median subjects T1m, T1n, m=round(t1/2), n=m+1, the two median subjects T1m, T1n are vertically spaced by R, and are symmetrically distributed on both sides of the midline of the central subject.

If the total number of subjects at level 1 is odd, the formula for calculating the T1m coordinate value of the median subject at level 1 is as follows:

T1m starting point abscissa = center theme length + PC version spacing = LT0 + C;

T1m starting point ordinate = - 1st level subject height / 2 = - HT1/2;

The abscissa of the end point of T1m = the length of the central theme + the spacing of the PC version level + the length of the first level theme = LT0+C+LT1;

T1m end point ordinate = 1st level subject height / 2 = HT1/2;

T1m parent connection point abscissa = center theme length + PC version spacing = LT0 + C;

T1m parent connection point ordinate = 0;

T1m sub-connection point abscissa = central theme length + PC version level spacing + 1st level theme length = LT0+C+LT1;

T1m child connection point ordinate = 0;

If the total number of subjects at level 1 is an even number, the formula for calculating the T1m coordinate value of the median subject at level 1 is as follows:

T1m starting point abscissa = center theme length + PC version spacing = LT0 + C;

T1m starting point ordinate = PC version level inner distance/2= R/2;

The abscissa of the end point of T1m = the length of the central theme + the spacing of the PC version level + the length of the first level theme = LT0+C+LT1;

T1m end point ordinate = PC version level inner distance / 2 + 1st level theme height = R/2 + HT1;

T1m parent connection point abscissa = center theme length + PC version spacing = LT0 + C;

T1m parent connection point ordinate = PC version level inner distance/2 + 1st level theme height/2= R/2+HT1/2;

T1m sub-connection point abscissa = center theme length + PC version level spacing + 1st level theme length = LT0+C+LT1;

T1m sub-connection point ordinate = PC version level inner distance/2 + 1st level theme height/2= R/2+HT1/2;

After the median topic T1m determines the coordinates and position, other topics in the first level are based on T1m, left-aligned with T1m, and vertically separated by 1 or more R line spacing, then their starting point coordinates, end point coordinates, parent Connection point coordinates, sub-connection point coordinates, if the serial number is less than m, the serial number is from large to small, in the vertical direction, above the T1m topic, and the distance from the T1m topic is 1, 2, 3... R distances are arranged in order until T11 The coordinates are calculated, arranged, and displayed in the corresponding position. If the serial number is greater than m, under the T1m theme, the serial number is from small to large. In the vertical direction, the distance from the T1m theme is 1, 2, 3... The coordinates of the t1 theme with the largest serial number are calculated, arranged, and displayed in the corresponding position. After all the calculation results are written into the theme table, this step is all completed.

Topic T1j, j=1, 2, ..., t1, T1j coordinate values of the first-level serial number j are calculated as follows:

The abscissa of the starting point of T1j = the abscissa of the starting point of T1m;

T1j starting point ordinate = T1m starting point ordinate + (m-j)*(R+HT1);

The abscissa of the end point of T1j = the abscissa of the end point of T1m;

T1j end point ordinate = T1m start point ordinate + (m-j)*(R+HT1);

The abscissa of the parent connection point of T1j = the abscissa of the starting point of T1m;

T1j parent connection point ordinate = T1m parent connection point ordinate + (m-j)*(R+HT1);

T1j sub-connection point abscissa = T1m end point abscissa;

T1j sub-connection point ordinate = T1m sub-connection point ordinate + (m-j)*(R+HT1);

The calculation method of the picture starting point coordinates and the picture ending point coordinates of the T1j theme is as follows:

The abscissa of the picture starting point of the T1j subject = the abscissa of the starting point of T1j - C/2;

The ordinate of the picture starting point of the T1j subject = the ordinate of the starting point of T1j - R/2;

The abscissa of the picture end point of the T1j theme = the abscissa of the start point of T1j - C/2 + the width of the PC version picture;

The ordinate of the end point of the picture of the T1j theme = the ordinate of the start point of T1j - R/2 + the height of the PC version picture.

Step S208: Calculate the starting point coordinates, end point coordinates, parent connection point coordinates, child connection point coordinates, picture start point coordinates, and picture end point coordinates of the second level of the left and right structure of the PC version and all subsequent topics, and use the set font, font size, color, arrangement direction, etc., display the subject and picture in the corresponding position, and write the result into the subject table:

In the left and right structure, any one topic in the lower level topic is a subtopic of a certain topic at the upper level. The upper level topic is the parent topic, and the lower level topic is a child topic. or more, the subtopics are arranged on the right side of the parent topic, the centerline of the parent topic and the centerline of the subtopics are parallel to the X axis and extend to the +X axis direction, the topic text heads up, from left to right, horizontally to the left, horizontally In the direction, the minimum distance between the head of the child theme and the tail of the parent theme is the PC version level distance C, and in the vertical direction, the minimum distance between the adjacent topics in the hierarchy is the PC version level distance R.

Filter out all topics with level number = 2 from the topic table, and sort them from small to large. Start with T21, first find the parent topic T1x of the topic, and then filter out the parent topic from the topic table as T1x , all topics with level number = 2, and sort them from small to large within the level, and calculate the total number t2. When the total number of subtopics t2 is odd, there is a median topic T2m, m=rounded (t2/ 2)=round(t2/2), the center line of T2m topic coincides with the center line of parent topic T1x, when the total number of subtopics t2 is an even number, there are 2 median topics T2m, T2n, m=round(t2/2), n=m+1, the two median subjects T2m and T2n are vertically separated by R, and are symmetrically distributed on both sides of the parent subject T1x midline.

According to step S207, the calculation method of all topics starting point coordinates, end point coordinates, parent connection point coordinates, child connection point coordinates, picture start point coordinates, and picture end point coordinates of the first level of the left and right structure of the PC version, using the above calculation results, T21, T22, T23... ...up to the start point coordinates, end point coordinates, parent connection point coordinates, child connection point coordinates, picture start point coordinates, and picture end point coordinates of the last topic of level 2 are calculated, display these topics and pictures in the corresponding positions, and write the result. into the subject table.

Continue to repeat the above steps, according to the above calculation method, using the above calculation results, you can use the third level, the fourth level... to the last level of all topics starting coordinates, end coordinates, parent connection point coordinates, child connection point coordinates , The coordinates of the starting point of the picture and the coordinates of the end point of the picture are calculated, these themes and pictures are displayed in the corresponding positions, and the results are written into the theme table.

Step S209, connect the parent connection points of all themes and the child connection points of the parent theme with the set connection line style and width, and display them with the set color.

The connecting line styles include: equal thick arc, tapered arc, equal thick S line, tapered S line, equal thick polyline, etc. They are drawn using different line drawing libraries.

Equal thickness arc drawing method: If the ordinate of the child connection point of the parent theme is equal to the ordinate of the parent connection point of the theme, the equal thickness arc becomes an equal thickness straight line, then the child connection point coordinates of the parent theme and the theme's parent The coordinate of the connection point is a parameter, which is drawn according to the width of the same thick arc, using the straight line drawing class library, and displayed according to the set color; if the ordinate of the child connection point of the parent theme is not equal to the ordinate of the parent connection point of the theme, Then according to the width of the arc of equal thickness, using the coordinates of the child connection point of the parent theme, the control point, and the coordinates of the parent connection point of the theme as parameters, it is drawn using the second-order Bezier curve drawing class library, and it is drawn according to the set color. Display, wherein the control point coordinate selection method is: the abscissa of the control point is greater than the abscissa of the child connection point of the parent theme, smaller than the abscissa of the parent connection point of the theme, and the ordinate of the control point is equal to the ordinate of the parent connection point of the theme.

The drawing method of the tapering arc: the tapering arc is composed of the left vertical line, the right line, the upper arc and the lower arc, and is filled and displayed according to the set color of the tapering arc. Among them, the coordinate of the starting point of the upper arc is the parent The coordinates of the sub-connection point of the theme are vertically moved up by half the width of the tapered arc, the coordinates of the starting point of the lower arc are the distance of the sub-connection point of the parent theme, and the coordinates of the end point of the upper arc are vertically moved down by half the width of the tapered arc. The coordinates of the parent connection point of the theme are vertically moved up by half the width of the tapered arc multiplied by the distance of the tapering ratio of the connection line, and the coordinates of the end point of the lower arc are the coordinates of the parent connection point of the theme. With the distance of the connecting line tapering, the left vertical line is drawn with a straight line class library, which is drawn by connecting the coordinates of the starting point of the upper arc and the starting point of the lower arc, and the right line is drawn with a straight line. It is drawn by connecting the coordinates of the end point and the end point of the lower arc; if the ordinate of the child connection point of the parent theme is equal to the ordinate of the parent connection point of the theme, then the upper arc becomes a straight line, then the coordinates of the starting point of the above arc, the upper arc The coordinate of the end point of the line is the parameter, and the upper arc is drawn using the straight line drawing class library. If the ordinate of the child connection point of the parent theme is not equal to the ordinate of the parent connection point of the theme, the coordinates of the start point, upper control point, upper The coordinate of the end point of the arc is a parameter, and the upper arc is drawn using the second-order Bezier curve drawing class library.
