Recording Zoom factor and Pan position for intensity graph (LV8.2/8.5)

[DonRoth]

I'm using the zoom and pan features on the graph palette.  I need a way to determine the zoom factor and pan position so as to reapply these to another intensity graph.  Any way to do this?

Thanks,

Don

Can't you just copy over the Xscale.range.min|max and yscale.range.max|min?

[DonRoth]

I think this would work.

Since I am using an event-based architecture, I probably could take the strategy of using a mouse move event to grab scale information during panning, and a mouse down or up event to grab scale information during zooming.

I'll give this a shot and post a message on my results.

Sincerely,

Don

Yes, this looks like it will work - I have an additional complication in that I am applying a 2d interpolation upon zooming, but I should be able to calculate the appropriate scale ranges based on the interpolation factor and the initial pan location. I just created one case for both mouse events to record the ranges.

Thanks again for your help.

Sincerely,

Don
