Hi, I am not managing to ge matplotlib to work with the new Ubuntu realease hardy 8.04.

[Matplotlib-users] Legend for a scatter plot based on symbols
Hi, I'd like to plot three scatter plots on the same figure, each with different symbols. Associated to these scatter plots, I'd like to put a legend. For the moment, the legend is based on one of the color of the associated scatter plot, but it is not relevant. Indeed, the colors are not identical inside one scatter plot, so the displayed color is discriminating. So I'd like to display the symbol (circle, square, cross, ...) instead of the color rectangle. Is it possible ?

Re: [Matplotlib-users] Ubuntu Hardy and matplotlib
I'm somewhat grasping at straws here: the Ubuntu-packaged matplotlib
works for me on Hardy.
Thanks. Ubuntu puts the matplotlib data files in a separate package,
python-matplotlib-data. That *should* have installed automatically
alongside python-matplotlib, but you may want to try forcing that:
sudo apt-get install python-matplotlib-data
If that fails, try reinstalling both python-matplotlib and
python-matplotlib-data.
sudo apt-get install --reinstall python-matplotlib
The second error also seems like another instance of the same: the
python-dateutil package should be installed.
Cheers,
Mike

[Matplotlib-users] Robinson projection imshow out of bounds and different latitude limits
Dear all!
I would like to ask two questions: one concerning imshow with the
Robinson projection and the second about the latitude limits for the
same map projection.
First, I am trying to make a Robinson projection map using imshow
instead of contourf as described in the Basemap documentation. I
modified the script as follows:
#--
from matplotlib.toolkits.basemap import Basemap, shiftgrid
from pylab import load, meshgrid, title, arange, show, cm, pi
#
# read in topo data (on a regular lat/lon grid)
etopo = load('etopo20data.gz')
lons = load('etopo20lons.gz')
lats = load('etopo20lats.gz')
#
# create Basemap instance for Robinson projection.
m = Basemap(projection='robin',lon_0=0.5*(lons[0]+lons[-1]))
#
# compute native map projection coordinates for lat/lon grid.
etopo, lons = shiftgrid(180., etopo, lons, start=False)
x, y = m(*meshgrid(lons,lats))
dx = 2.*pi*m.rmajor/len(lons)
nx = int((m.xmax-m.xmin)/dx)+1; ny = int((m.ymax-m.ymin)/dx)+1
dat, x, y = m.transform_scalar(etopo, lons, lats, nx, ny, returnxy=True)
#
# make filled contour plot.
im = m.imshow(dat, cmap=cm.jet)
m.drawcoastlines() # draw coastlines
m.drawmapboundary() # draw a line around the map region
m.drawparallels(arange(-90.,120.,30.),labels=[1,0,0,0]) # draw parallels
m.drawmeridians(arange(0.,420.,60.),labels=[0,0,0,1]) # draw meridians
title('Robinson Projection') # add a title
show()

The result looks as I would expect, except that some data is plot
outside of the map boundaries. Using another projection as the
Orthographic for example, this problem doesn't happen. Am I doing
something wrong?
Second, I work with Topex/POSEIDON and Jason-1 sea surface height
anomalies datasets where the latitudes range from about 67.5S to 67.5N.
Outside these limits hopefully its blank, as anyone would expect.
Aesthetically I find it more appealing if I could limit my map
boundaries to these limits, or even lower limits if I zoom the
equatorial region. Has anyone ever tried to do this?
Thank's in advance and kind regards,
Sebastian
