Zooming and Panning in Lw-CVI

[AutomationCVI]

Are there any other metode to activate "Zooming" and "Panning" ( and ecc) for Graph control in LabWindovs_CVI, like press an icon in LabView ? How can i do this?

No, that is the only built-in way to do it with the CVI graph. There is no graph palette like the one for the LabVIEW graph.

Thank you so much for your quick response.
Do you know if there are external library (like *.FP) to perform graph 2D with zooming and panning whitout keyboard use? The users found not user-frendly to use or or .
Thanks

Actually, yes. I forgot that in CVI 6.0 there was a custom control that was added that is a palette for working with graph cursors. (You can find an example under cvi\samples\userint\custctrl\graphcursors\) This palette allows you to zoom in a new way by positioning two cursors, selecting them (using the select button on the palette), and then zooming to the area confined by the two cursor positions. Take a look at the example program and see if that will be an acceptable way for you to zoom.
