Embodiment 1
[0038] This embodiment provides a waveform display method, including:
[0039] Dividing the screen into at least one display area, outputting at most one waveform display data to each display area and displaying it;
[0040] When the waveform shift indication information is received, the following processing is performed:
[0041] determining the pre-shifted waveform, the original display area and the pre-shifted-in display area according to the waveform shift indication information;
[0042] stop outputting the display data of the pre-shift waveform to the original display area;
[0043] When it is determined that no waveform is currently displayed in the pre-shifted display area, the display data of the pre-shifted waveform is directly output to the pre-shifted display area for display; when it is determined that the pre-shifted display area displays the occupied waveform, the The display data of the occupied waveform is output to other display areas outside the pre-shift ...

Abstract
The invention provides a waveform display method and display device. The method includes: segmenting a screen into at least one display area, and outputting and displaying display data of at most one waveform to each display area; when a waveform shift indication information is received, executing the following processing processes: a pre-shift waveform, an original display area and a pre-shift-in display area are determined according to waveform shift indicating information; display data of the pre-shift waveform are stopped from being output to the original display area; when the pre-shift-in display area is determined not to display a waveform at present, the display data of the pre-shift waveform is directly output to the pre-shift-in display area for display; when the pre-shift-in display area is determined to display an occupied waveform, display data of the occupied waveform are output to another display area outside the pre-shift-in display area, and the display data of the pre-shift waveform are output to the pre-shift-in display area for display. The waveform display method provides a relatively direct observation effect for a user, and omits the trouble of frequent shift operation for waveform observation.
Description
technical field [0001] The present invention relates to the technical field of waveform display, in particular to a waveform shift display method and a display device. Background technique [0002] Common waveform display devices such as oscilloscopes can usually display the waveforms of multiple acquisition signals at the same time. The display features are usually: the device screen is divided into multiple display areas, and the waveforms are displayed in these display areas. Multiple channels can be displayed in the same display area. These waveforms cover each other, and the lower waveform can only be displayed after the upper waveform is shifted; figure 1 As shown, waveform 1 in display area A covers waveform 2. To observe waveform 2, waveform 1 needs to be shifted, as shown in figure 2 As shown, when waveform 1 is moved from display area A to display area B, waveform 2 can only be observed in display area A, but at the same time, waveform 3 originally displayed in d...
