[Matplotlib-users] Map projections and pyplot.plot

2011-12-01 Thread Bruce Ford 
I have a basemap figure where data is placed atop, which can be in any
number of differing projections.  However, when I plot a line over it using
pyplot.plot, the line doesn't show unless I'm using
the cylindrical equidistant projection.

>From what I gather this is a limitation of the plot command.  Can anyone
confirm this?  Is this a limitation in that the 'cyl' projection is assumed
by pyplot.plot?

I saw a post that mentioned that a projection kwarg would not be added to
the plot command.  Does this mean that the plot command will realize the
projection of the gca basemap?

[Matplotlib-users] ft2font.cpp memory fix patch not in 1.1.x branch

2011-12-01 Thread Neilen Marais 
Hi,

We are (I think) running into a memory leak that should be resolved by

https://github.com/matplotlib/matplotlib/commit
/98ee4e991ae142622f3814db193b75236eb77cea#src/ft2font.cpp

It was commited in March, but seems not to have made its way to the 1.1.x
branch. Would it be possible for a maintainer to apply it to the release branch?

Thanks
Neilen

Hmm, strange...

It isn't even in master right now.  The last changes to it were by Michael
Droettboom (commit 6b643862) in June of 2010, but the commit you are
pointing to was done in March of 2011... this needs more investigating.

Strange, I could have sworn that I rebased my master branch correctly.
Now, the fix is showing in master.  Well, now that that has been resolved,
I guess we can just simply cherry-pick that commit into v1.1.x?

Bruce:  Did you convert the coordinates of the data you're plotting with 
pyplot.plot to map projection coordinates (by passing the lat/lon values 
to the Basemap instance)?

Yes, as a matter of fact I create an identical basemap object as the
plotted gridded data.  And the lines (tropical cyclone tracks) plot fine as
long as the projection is 'cyl'.

 Can anyone confirm this?  Is this a limitation in that the
'cyl' projection is assumed by pyplot.plot?
