Dear Group,
Consider the following two examples from the RegionPlot documentation
(Under PlotStyle):
p1=RegionPlot[(x + 1)^2 + y^2 < 2 || (x - 1)^2 + y^2 < 2, {x, -3, 3},
{y, -3, 3}]
p2 = RegionPlot[{(x + 1)^2 + y^2 < 2, (x - 1)^2 + y^2 < 2}, {x, -3,
3}, {y, -3, 3}]
At least in my system (Mac OS 10.7, Mathematica 8.0.1), the quality of
the graphs are entirely different. Moreover, if I wrap them in a
GraphicsGrid, p2 appears with it's mesh wheres p1 doesn't.
GraphicsGrid[{{p1}}]
GraphicsGrid[{{p2}}]
This seems like a problem with Opacity, for if I insert
PlotStyle -> Lighter[ColorData[1, "ColorList"], 0.75]
into p2, the problem is solved.
Is this a bug, or am I missing something?
Thanks in advance,
Gabriel
