Re: [matplotlib-devel] problems with labeling contour lines in 0.98.3

David -

Enjoy your vacation.

I tried the contour_label_demo and it works fine, but my problem remains.

I suggest you try the example I provided below, and notice the difference
between labeling with inline=True and inline=False. When inline=True the
contours in the middle part (which don't get labeled, presumably because
there isn't enough room) get erased.

I figured out the manual input problem. The trick is that you require to
press the middle button to end (I'll do a post to the user's list). Many
laptops don't have a middle button. Although suggestions are found on the
web that pushing both buttons simultaneously works, I have never seen it
work. What you have to do is configure your touchpad such that a corner acts
as the middle button. Once I figured that out, I could end manually
selecting the labels. Very nice. If I may, I strongly recommend you change
the code such that pushing the right button ends the manual input. Is there
any reason not to use the right button for that?

I hope you can fix the inline problem. Thanks for all the other new cool
features,

Mark
