How to pause the waveform chart display by a boolean control?

[billkaiser]

I want to dislay data point by point through a waveform chart and pause it by a boolean control named pause. If it is pressed, the waveform chart will pause displaying and will continue when it is repressed. How to realize tjhe above function?

Hi,
Is this what you need?

Put a case statement around your acquisition/chart code and wire the control to it. It's easiest to have the mechanical action to Switch When Pressed and have the Boolean text say Pause in one state and Resume in the other state but if you want a momentary acting switch, you can add some logic with a shift register. Here's a simple example in LV 6. You should also look at the pause and resume state machine example available here.

I believe the quickest way to do this is to put the Chart inside a case structure, and wire the selector to a boolean control. You can choose the "behavior" of the control on the front panel by right clicking it and selecting the MECHANICAL action. You can choose the PUSH ON/PUSH OFF to simulate your desired behavior.

Good Luck!
