How do you ensure the plot area of an overlayed graph matches the plot it overlays?

[Chris Bailey]

I'm trying to plot a boundary contour using an xy graph over an intensity graph. The scales in the intensity graph, which are not displayed, are simply the element numbers in the array, but in the xy plot these have been converted to the real values, and are displayed. The problem occurs when an extra digit appears in the y scale, the width of the border is increased and hence the xy plot is displaced from the intensity plot.
Is there a way to stop this?
The plot areas are matched using property nodes, as can be the position of the top corner of the graphs including borders, however the width of the border is a read only function.

I'm not sure if this will work, but you can try putting this line in your labview.ini file

EnableAutoScales=False

This sometimes helps fix resizing problems. If that does not work, you do have control over the plot area size and position, you may be able to use these to compensate.
