how draw a rectangle area in the signal wavefrom

[EricYuanHongbo]

Dear all, I use the DAQ card to acquire a analog signal, this is a riseing wavefrom from 0 to someone voltage value, but I only want to check someone rectangle area signal value, so I want to draw a rectangle are in th waveform, use to show I will check signal in this area, how can I draw it in the labview? Best Regards, thank you.

Please show us a simplified version of your code, because we don't have sufficient information:

• How do you plot the data (chart, graph, xy graph, etc.)
• Do you want a real rectangle (range limit in x and y) or just limits in y?
• You should do limit checking in code, not leave it to the user to determine if a point is inside or outside.

Please attach your code and explain what you like to see.

Dear

 Thank you and I got your feadback.

 I use a evaluation version to study it, and this a requirement for the furture project, and I think that maybe need a real rectangle display on the signal waveform, and directly show the status, haven't write a program, only to try it us more way to do.

Best Regards.

Thank you.
