* summary: [with patch; needs review] plot_region function => [with
patch; needs work] plot_region function
Comment:
This has some odd behavior which I hope the author could please comment
on:
This looks good:
{{{
sage: P1 = region_plot(cos(x^2+y^2) <= 0, (-3, 3), (-3, 3), incol='green',
bordercol='red')
sage: show(P1)
}}}
This looks very odd (wrong but maybe the algorithm just needs more
points?):
{{{
sage: P2 = region_plot(cos(x^2+y^2) <= 0, (-30, 30), (-30, 30),
incol='green', bordercol='red')
sage: show(P2)
}}}
This looks plain wrong (and I think we have provided enough points:-):
{{{
sage: P3 = region_plot(cos(x^2+y^2) <= 0, (-30, 30), (-30, 30),
incol='green', bordercol='red', plot_points=1000)
sage: show(P3)
}}}
