Dear all,
We want to overlay to contourplots, so we do
ContourPlot[{x^2/4 + y^2/16}, {x, -6, 6}, {y, -5, 5},
Contours -> {1.},
ContourShading -> {{Red, Opacity[0.4]}, Opacity[0.]},
ContourStyle -> Opacity[0.2]]
ContourPlot[{x^2/25 + y^2/9}, {x, -6, 6}, {y, -5, 5},
Contours -> {1.},
ContourShading -> {{Blue, Opacity[0.4]}, Opacity[0.]}]
Show[%,%%]
The question is that when we do Export["contours.ps",%] the resulting
image has a black area in the non-coloured region, which appears white
on the screen. No problem when exporting to pdf.
Is there some replacement rule which will do the trick?
Thanks a lot,
Ruth Lazkoz
