[vtkusers] Setting the X axis of VtkChartsXY

[Darshan Pai]

Thanks Marcus , it works

I do have one more question though . Is there any way to change the
tooltip? I mean that when you hover the mouse on the line, I get the x and
y axis value of the point. Since I have custom labels for the X axis, can I
also modify the tooptip value to reflect that label.

Regards
Darshan
