I am using Plot XY.vi for a picture output (not XY graph.) I would expect if w =h, that the grid would be square. The grid scale is

not consistent between X and Y, would prefer using my own scale. I will be overlaying symbology on the grid picture using vi's which place the symbology at pixel locations. How can I find out how the pixel locations correspond to the original grid scale.Also, the cartesian axis attributes don't seem to work correctly. x, y min and max have no effect on scaling the graph if the input data is 0.

I am a beginner use of LabView.
LabVIEW version 6.0 (soon to be upgraded to latest).
Thanks.

The Plot XY is a VI and you might want to look at some of its
implementation. I suspect that the width and height are the outer
extent, not the inner rectangle. You should be able to work backwards
to det
ermine the rectangle needed to make the grid be square. For the
problem with min and max x and y values, you should make sure that you
don't have autoscaling turned on as that will override the scale values.
