When the result data is configured with dynamic parameters, so that a graph is created at the position of the graph drawing area, the parameters on the horizontal axis and the vertical axis are directly in one-to-one correspondence, and when the graph is created, points corresponding to the parameters are directly drawn on the graph, as shown in fig. 4, and the points are connected one by one according to the sequence corresponding to the horizontal coordinates of the points to form the graph.
Further, after the data in the configuration file is loaded into the memory, the dynamic data in the configuration file is operated to obtain result data, the result data is also loaded into the memory, after the result data is loaded into the memory, the data information in the memory is read, the data information is converted into a coordinate point parameter with a horizontal axis parameter and a vertical axis parameter, the height and the width of the curve graph are determined, and the vertical axis parameter of the coordinate point parameter is compared with the height of the curve graph.
If the vertical axis parameter in the coordinate point parameters is larger than the height of the curve graph, the corresponding proportion of the height of the curve graph and the vertical axis unit is adjusted, so that the vertical axis parameter can be smaller than the height of the curve graph after the corresponding proportion is adjusted, and the vertical coordinate of the coordinate point parameter does not exceed the height range of the curve graph when the coordinate point parameter is drawn into the curve graph.
Further, the updating unit 94 is configured to:
and adjusting the coordinate point information in the curve graph according to the updated frequency information so that the curve graph after the coordinate point information is adjusted is the current real-time curve graph.
Determining the update frequency information, and if the update condition indicated by the update frequency information is currently reached, such as: when the curve graph currently displayed on the display interface is displayed for a preset time, or the latest data is currently received, or the preset curve graph updating time is reached, coordinate point information in the curve graph is adjusted, and an updated data is added.
Specifically, adding an updated data may be: adding a moment after the last moment of the abscissa of the curve graph in the curve graph, and displaying the data of the ordinate corresponding to the moment on the display area of the curve graph so that the updated curve graph is the curve graph added with one updated datum;
alternatively, the following may be used: and deleting all points and lines in the display area of the currently displayed curve graph, re-determining a plurality of coordinate points to be updated, and connecting the plurality of coordinate points to form the updated curve graph.
Further, the method can also comprise the following steps:
determining the current time as the coordinate point information updating time based on the updating frequency information, and acquiring the coordinate information of the current time; deleting coordinate information of a first moment in the graph, wherein the first moment is a moment adjacent to an origin of a coordinate axis on a first axis, and the first axis is an axis used for representing the moment in a horizontal axis or a vertical axis; translating coordinate information between a second moment and a third moment to the direction of the coordinate axis origin, wherein the second moment is a moment adjacent to the first moment, and the third moment is a moment which is separated from the first moment by a preset time length and is displayed on the first axis after the first moment; and determining the coordinate information of the current moment as coordinate information of a fourth moment in the curve graph, and displaying the coordinate information in the curve graph to obtain the current real-time curve graph after the coordinate point information is adjusted, wherein the fourth moment is a moment after the second moment and separated from the second moment by a preset time length.
Specifically, if it is determined that the update condition is currently satisfied based on the update frequency information, for example: when the current time reaches the coordinate point information updating time, the coordinate information of the current time is acquired, and at the same time, the coordinate information of the first time in the graph is deleted, as shown in fig. 6, the graph displayed on the display interface includes A, B, C, D, E, F, G seven coordinate points, which respectively correspond to seven sequential times of 1, 2, 3, 4, 5, 6, and 7 on the abscissa, and when the updating condition is satisfied, the time 8 is reached, the coordinate information of the time 8 is acquired, which corresponds to the H coordinate point.
The graph is a graph including only six coordinate points B, C, D, E, F, G as shown in fig. 7, in which coordinate information of the first time in the graph, that is, the point a of the time having the abscissa of 1 is deleted, and the coordinate point between the second time and the third time is shifted in the direction of the origin of the coordinate axis, that is, the coordinate point B, C, D, E, F, G corresponding to the six times having the abscissas of 2 to 7 is shifted in the direction of the origin of the coordinate axis.
The coordinate information of the current time is determined as the coordinate information of the fourth time in the graph, and is displayed in the graph, that is, the coordinate point H of the time 8 is displayed in the graph, as shown in fig. 8, so as to form an updated graph, and achieve the purpose of updating the graph in real time.
The graph generating method disclosed in this embodiment obtains a configuration file, where the configuration file at least includes basic parameter information for configuring a real-time graph, update frequency information of the real-time graph, and dynamic data, runs the dynamic data in the configuration file to obtain result data, generates a graph based on the result data and the basic parameter information in the configuration file, and updates the graph based on the update frequency information in the configuration file. According to the scheme, the result data are obtained by running the dynamic data in the configuration file, the curve graph can be generated based on the result data, and the curve graph is updated periodically based on the updating frequency information in the configuration file after the curve graph is generated, so that the curve graph updated in real time is obtained, and the problems that the display rule needs to be manually adjusted when the curve graph is updated, and the operation is inconvenient are solved.
