There will be a blank area in front of the insertion position of the new waveform point to separate the new insertion point and the old waveform point, so that it is difficult to view a complete single waveform, which is not conducive to the comparison and analysis between the two waveforms before and after
In the above two display methods, the user cannot effectively analyze a single waveform, and it is difficult to give an accurate analysis conclusion

Embodiment Construction
[0019] The present invention will be further described in detail below in conjunction with specific examples, but this does not constitute any limitation to the present invention. refer to image 3 with Figure 4 As shown in the present invention, a method for displaying waveforms in a small area in real time includes the following steps: (1) storing the waveform to be displayed in the buffer; (2) buffering the first wave in the buffer, that is, the last The waveform segment that first entered the buffer with a duration of A is moved out of the buffer within the duration of B and inserted on one side of the screen for display, and the old waveform is quickly moved out from the other side of the screen, and the value of A is greater than the value of B; (3) Buffering After the waveform with a duration of A is inserted, the waveform on the screen remains static, and the static time of the screen is the difference between the subtraction of A and B, waiting for the new waveform ...

Disclosed is a method for displaying a waveform within a small range in real time, belonging to the technical field of waveform display. The technical points thereof include the following steps: (1) storing a waveform to be displayed in a cache area; (2) rapidly inserting a waveform the cache duration of which is A into one side of a screen within duration B in the cache area for display, and rapidly moving out an older waveform from another side of the screen, with the value of A being greater than that of B; (3) completing the insertion of the waveform the cache duration of which is A, the waveform on the screen being static, with the static screen duration being the difference between A and B, and waiting for a new waveform the duration of which is A to be stored in the cache area; and (4) after the waveform the duration of which is A is stored in the cache area, repeating the abovementioned steps (2) and (3), until the display of the whole waveform is completed. The present invention is directed to provide a method for displaying a waveform within a small range in real time which is intuitive in display and convenient for viewing and used for real-time display of waveforms.
Description
technical field [0001] The present invention relates to a method for displaying waveforms, more specifically, a method for displaying waveforms in real time in a small area. Background technique [0002] There are two main modes of existing waveform display modes: rolling mode and overlay mode. Rolling display mode: the old waveform moves from right to left on the screen, new waveform points are inserted to the far right continuously, and the oldest waveform in the display will continuously move out of the left end, the display mode is as follows figure 1 shown. This display method is essentially caused by the time axis moving to the left continuously with the passage of time. Since the waveform moves continuously and at a high speed, it is difficult for the user to clearly view a single waveform and analyze a single waveform. Overlay display: The position of the old waveform on the screen remains unchanged, and the new waveform points will continuously cover the old wavef...
