Comment (by wdj):
Okay, thanks for that explanation. This is a useful patch.
My impression is that if it can't be easily fixed, then at least it should
be documented how to adjust the parameters to get proper behaviour. I'm
guessing that the people who will use this patch are students and
teachers, so the more detailed examples the better:-) Does this seem
reasonable?
With that's I'd be prepared to give it a positive review.
Other cool examples you could include:
{{{
sage: region_plot(x*(x-1)*(x+1)+y^2<0, (-3, 2), (-3, 3),
incol='lightblue', bordercol='gray', plot_points=400)
sage: region_plot([x*(x-1)*(x+1)+y^2<0, x>-1], (-3, 2), (-3, 3),
incol='lightblue', bordercol='gray', plot_points=400)
}}}
And one similar to Jason's:
{{{
sage: P = region_plot([x^2+y^2<4, x>-1], (-2, 2), (-2, 2),
incol='lightblue', bordercol='gray', plot_points=400)
sage: P.show(aspect_ratio=1)
}}}
(I know you have
{{{
region_plot([x^2+y^2<1, x<y], (-2,2), (-2,2))
}}}
but it looks odd without the aspect ratio set.)
Do these seem reasonable Arnaud?
