The picture VIs take in a rectangle telling them where to draw and how
large. When you drop the Polar plot from the panel, it automatically
drops a property node to read the picture rectangle and pass this in.
This rectangle can also be used to put multiple plots in the same
picture in any sort of grid you like.
Anyway, you can either change the rectangle yourself or tie it to the
picture control rectangle.
As for displaying the scale differently, this will take a bit more work.
First opent he hierarchy window under Browse. There are two VIs, PG
angle labels.vi and PG scale.vi that draw the text labels on the polar
plot. It sounds like you want to mofidy the PG scale to move the labels
to be drawn on the grid lines rather than on the extensions. The key to
making this easier to debug is to open up this subVI panel and then run
your app. This will leave the values the subVI is normally run with in
the subVI controls. Then make the picture in and out larger and start
making modifications to the diagram. Once you get to this point, the
simple trig and graphics math is all that is needed.
