Re: [Matplotlib-users] bug in labeling contour lines

[Mark B. <ma...@gm...>]

A little follow-up.
When I use keyword argument inline=False, it doesn't remove the lines
without a label.

So it seems that when using inline=True the unlabeled contours get a white
box, but no label (because it doesn't fit) which essentially removes the
entire contour.
