Comment:
Works as advertaised, but region_plot gives error after installing this
patch.
{{{
sage: x,y=var('x y')
sage: region_plot(cos(x^2+y^2) <= 0, (x, -3, 3), (y, -3, 3))
Traceback (click to the left of this block for traceback)
...
KeyError: 'linewidths'
}}}
did you try this?
{{{
./sage -t devel/sage/sage/plot/contour_plot.py
}}}
My patch fixes long lines (which make help for contour_plot too wide for
typical screen) and split contour_plot exmaples into groups (this allows
to try commands immediatelly when reading live reference manual).
One suggestion: could we set label_colors to something resonable (gray?
red? blue?) when both fill and labels are True, but label_color is not
specified?
