Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Core concept of the present invention is to allow waveform equal proportion overlapping to solve the problem of waveform cut-off, and meanwhile, waveform equal proportion is overlapping can also be played and waveform arranged reasonably act on and reach the effect that waveform is easily differentiated.Waveform equal proportion is overlapping to be referred in all waveforms, and the ratio that the superimposed part of waveform accounts for its whole waveform height is consistent.
Fig. 1 is the flow chart of the waveform drawing method of the embodiment of the present invention.Please refer to Fig. 1, this waveform drawing method comprises the steps:
S1, obtain the step of N waveform.
This step is the basis of waveform drawing, obtains for drawn waveform, allows drawing have object, shoots the arrow at the target.In this step, this N is greater than 1 natural number, and the numerical value of N is not particularly limited in the present invention.For example, ecg wave form has at present 12 leads, 15 leads etc., and these waveforms just have 12 waveforms, 15 waveforms, and now N is 12 or 15 or other numerical value.For patient monitor, this N is just for showing quantity or other numerical value of physical signs.Generally, the Wave data obtaining is kept in memorizer required in order to picture ripple.
