Moving cursor to Zoomed Position in waveform graph

[pratheek]

Hello

I have 2 cursors in my waveform graph and I would like to have the cursors move to the zoomed in position of the graph when I zoom in or out of the graph. Could some please tell me how to do it. Thankyou in advance

There is a scale range event that fires when either of the scales are changed. Put logic there to reposition the cursors within the zoomed area as needed.

HI Mike

Thanks for the reply. When I apply the logic to reposition the cursor in the scale range event only one cursor is moving to the zoomed in position. The other cursor remains out of  graph scale. I tried to repeat the same logc but it didn't work.  Could you please tell me how to get the 2nd cursor also in to the scale range. Sorry i'm fairly new to labview. I have attached the pic of what I tried.  Thankyou in advance

You have to first write to the active cursor property.

You have to write first to the active cursor before writing the new position. Your write is in the wrong place.

The thing to remember is that property nodes are one of the few places in LV where physical position matters. Property nodes always "execute" from top to bottom.
