Thanks for the response. drawlsmask gets the job done.

Jon: It's a know issue. From the KNOWN_BUGS file:

* The fillcontinents method doesn't always do the right thing.  Matplotlib
always tries to fill the inside of a polygon.  Under certain situations,
what is the inside of a coastline polygon can be ambiguous, and the
outside may be filled instead of the inside.  To trigger this,
run the garp.py example with lon=-71,lat=-33 (Santiago, Chile).
Workaround - mask the land areas with the drawlsmask method instead of
filling the coastline polygons.

I am creating projections centered around various locations:


m = Basemap(width=best_width, height=best_height, lon_0=centerLon
lat_0=centerLat, resolution='c',area_thresh=10000.,projection='laea')

For every location, i have the same code to fill the regions:
 
m.fillcontinents(color='#997766',lake_color='#99ffff',zorder=1)
> m.drawcoastlines(color='#000000', zorder=3)
> m.drawcountries(color="0.75", zorder=2)
> m.drawmapboundary(fill_color='#99ffff', zorder=0)
> 
For most regions, this results in the expected plot (
http://www.nabble.com/file/p23451317/good.png good.png )
However, whenever the region includes South America/Antarctica,
fillcontinents will color the entire map (
http://www.nabble.com/file/p23451317/bad.png bad.png )

Is this a known issue, and is there a way to circumvent it?

Thanks,
Jon

Hi, would it be possible to add a keyword to clabel to optionally switch off
the angle fix in contour.py lines 384+?


# Fix angle so text is never upside-down
        if rotation > 90:
            rotation = rotation - 180.0
        if rotation < -90:
            rotation = 180.0 + rotation


Something like "clabel(CS, upsidedown=True)" with the default as False would
do it.

I am using clabel to put directional arrows on a streamline contour plot,
and this rotation causes some of the arrows to point the wrong way.  So it
seems it would be a useful feature.  I'm willing to try to do it myself if
somebody could tell me which files I would need to edit in addition to
contour.py?

Many thanks,

Evan

The way Subversion works, 6887 is simply the latest revision in which
matplotlib/__init__.py was changed. If you have a Subversion checkout,
you can use the svnversion command to find out the revision of the
checkout. This could in principle be incorporated into the release
process to embed the latest revision somewhere in the source code.

I'd also check out wxMPL, it's a nice way to embedMPL in a GUI:

Hello,

I was wondering whether there is an easy way to find out the svn  
revision number of matplotlib in python. I tried:

In [2]: matplotlib.__revision__
Out[2]: '$Revision: 6887 $'

but this isn't actually the current revision number, I have upgraded  
to 7096 (I'm suspecting that 6887 is the revision number for 0.98.5.2)

I know it's probably unlikely that it's possible to find out the exact  
revision, but just wanted to check just in case!

Thanks,

Thomas

There isn't a way to do this in matplotlib itself -- none of the text 
matplotlib draws is interactive and selectable etc.

However, if you're embedded matplotlib in a wxPython GUI, you could 
stick a wxPython text widget underneath the plotting canvas and put 
whatever text you need there.  The details of that are more of a 
wxPython issue than a matplotlib one -- but you can see a number of 
examples of embedding matplotlib inside of a wxPython GUI here:

Cheers,
Mike

Hello!

I'm new to matplotlib and want to draw a line chart. Everythings works fine with the great matplotlib. Now my question:
I would like to draw under the diagramm a text, which can be selected and copied. Is this possible? I guess the easiest way is to do it over a GUI (I'm using wxPython). Please let me now if there's another (easier) way!

Kind regards
Stefanie
