Are you sure the "plots" lies are drawn, but are the same color as the background? I.e. a color
problem. The reason I ask is a similar thing happended to me today when I used COLOR=255. I
don't know enough about the WRITE_PNG routine to know if this is the issue or not (at least for
the first PLOTS although the second might screw up also if the color table is weird).
