Re: [Matplotlib-users] wrong link at http://matplotlib.org?

[Martin Spacek]

I think by download page, Keith meant project page.

The direct link seems to be http://sourceforge.net/p/matplotlib/mailman/ . Is
that permanent enough? Perhaps SF's structure has changed since the "lists" link
on the MPL website (http://sourceforge.net/mail/?group_id=80706) was last 
updated.

Re: [Matplotlib-users] Bug in Custom Dash List

[Jeffrey Spencer]

I think the function should be np.all(dash_list <= 0.0) instead of np.any?
This works 100% fine on my machine so I think it just hangs if all values
are less than or equal to zero. That hangs on my machine as you stated.

>From digging into that I also realized I could have put (None, None) to get
a solid line in my dash list which is what I desired but I think (1,0) is
more intuitive and doesn't cause any errors. Since dash lists have to be
even number of values, could not just put (1) to get a solid line.

I guess do whichever you think is better.

Cheers,
Jeff

Re: [Matplotlib-users] corrupt fonts problem

[Michael Droettboom]

You can set the rcParam "verbose.level" to "debug-annoying".  Then, when 
it runs through all of your fonts, it should be clear which one caused 
the problem.

Note that I'm in the process of rewriting large parts of the font 
infrastructure as part of MEP14, so these sorts of things should 
hopefully be less common in the future.

I think the usual advice here is to install the freetype development 
packages with MacPorts or homebrew -- but this is probably where I 
should step back at let one of the Mac OS-X folks speak up.

[Matplotlib-users] Figure editor fixes need testing

[Martin Spacek]

Hello,

I found an issue where the figure editor (the checkbox icon in the toolbar) 
incorrectly captures the color properties from the existing curves in the plot:

https://github.com/matplotlib/matplotlib/issues/2274

So I put together a pull request that fixes it:

https://github.com/matplotlib/matplotlib/pull/2275

Could we get someone (or someones?) to give it a whirl, make sure everything 
works as expected and that nothing obvious has broken?

Thanks,

Martin

There are no freetype* files in either place, no.  How would they get
there (other than an explicit install)?

Thanks again,

Which version of matplotlib are you using, and which backend?

import matplotlib
print matplotlib.__version__, matplotlib.get_backend()

[keith.briggs]

The last line of text below seems to say that setting block to either True or 
False causes an override of the blocking behavior.  I don't think this is as 
intended.   Which way round is it (in fact I find it has no effect)?

The problem I have is that using pyplot.show at the top level of a python 
script works correctly, but as soon as I out the same code inside a function, I 
see no plot.

How do I fix this?

Keith

http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.show

matplotlib.pyplot.show(*args, **kw)

In non-interactive mode, display all figures and block until the figures have 
been closed; in interactive mode it has no effect unless figures were created 
prior to a change from non-interactive to interactive mode (not recommended). 
In that case it displays the figures but does not block.

A single experimental keyword argument, block, may be set to True or False to 
override the blocking behavior described above.

[Matplotlib-users] corrupt fonts problem

[vwf]

Hello,

Matplotlib does not like one (or more) of my fonts. Since I own a
considerable set it is very hard to find out which one violates the
requirements. Is it possible to let matplotlib which font is the
problem?

Thanks

After building matplotlib 1.2.0 and basemap 1.0.6 packages for Debian
the problem is gone: I have coastlines now.
