Oh, right. I don't have time to work on this, but
I see in XPLOT (on my web page), I have had to size
the symbol according to the axes ranges. I've done
something like this:
; Size the symbols appropriately for the plot.
xSymSize = (xrange[1] - xrange[0]) * 0.015 * symSize
ySymSize = (yrange[1] - yrange[0]) * 0.015 * symSize
IF Obj_Valid(thisSymbol) THEN $
thisSymbol->SetProperty, Size=[xSymSize, ySymSize]
If I don't do that, the symbols are completely misshaped.
Cheers,
David
