active cursor

[gatordan82]

I have a graph, with two cursors.  I want to be able to move either cursor around, and then use the position of the last cursor that got moved.  I want to shift the data that I'm plotting (in the x-direction) so that the data's new "zero" point is at the position of the last moved cursor.

i'm using version 7.0

I'm not sure if you can do this "on the fly" since if you poll the cursors as they scroll, they'll constantly trigger changes (although you could probably stick a time delay in there to offset it).

When I use cursors to set graph ranges, I just use a "update graph" button and read the cursor positions to set the range.

You could use a Mouse Up event to trigger the scale change.  It is availible in 7.1, but I don't have a copy of 7.0 I can check.  Of course, that would execute each time the mouse is released.

great idea - and it works too
