Graphics.ScaleTransform With Negative Arguments

Dad
Hi,

I am trying to redefine the drawing coordinates of a window to
be 0.0 .. 1.0 in both axes with the origin at the lower left corner.
The origin transform (Graphics.TranslateTransform) works fine
but attempts to redirect the Y coordinate "upwards" with
Graphics.ScaleTransform(XScale, -YScale) results in a blank
screen. The call with positive values works as expected. What
is happening here? And what will do what I want?

Thanks,
Gary
