about catching the scale changed event for Intensity Graph

[PKIM]

Hi all,

  I am plotting an imange from a text file with each pixel separated by a delimiter to the intesnity Graph. I want to show the current time (with second) whenever the user changed the X or Y scale in runtime. I put a while loop to make it run until the stop is pressed. But in what way I could capture if the scale changed or not? I didn't work with the event handling code before, any suggestion to help me start is highly welcomed, thanks.

I am trying to attach the full code but it doesn't allow me to post anything in rar or zip format. So I post the image of the code as follows

Hi PKIM,

to "catch events" you should use the event structure.

There are several events for an IntensityGraph/Chart available…
