I want to plot contours on top of an image, using twinx and twiny for the
contour coordinates. I don't want to show the x- and yticklabels for the
contour coordinates. I find I can remove the xticklabels, but not the
yticklabels. There is mention of this problem here:

Hi, I have several path objects that I want to join together with
make_compound_path.
For example, with p1 and p2:
In [136]: p1
Out[136]:
Path(array([[-29.85721973, -30.],
[-29.84752676, -29.77715877],
[-29.88734508, -29.55431755],
[-29.97470553, -29.33147632],
Hi, I get unexpected behaviour using the script below. xticks only appear in
the 4th subplot. If the lines marked ### are moved out of the loop (and edited
so that they are constants), then xticks do appear on each subplot. Is this a
bug or am I missing something?
I am using matplotlib 1.1.0svn

Hi, I've just upgraded to mpl 0.99 (from svn) and Basemap (also from svn).
It seems that plt.clim(vmin,vmax) no longer works with Basemap
objects. Here is an example, which before used to work:
In [92]: M.pcolormesh(x, y, a_var,cmap=cm)
Out[92]:
In [93]: plt.clim(-10,10)

Thanks for that:
def ifmissing(x):
try: return float(x)
except: return np.nan
works just fine.

Hi, I want to put arrows onto the contours of a contour plot, the direction
will depend on whether the contour is positive/negative. Before I try to do
it myself, has anybody written something to do that?

Hi, wonder if anyone can help me with path and bbox. I have a set of ocean
drifter tracks and I want to know if they pass through a particular boxed

matplotlib.transforms and matplotlib.path, which look well-suited to this

Hi, I am having some problems using the oblique mercator projection in
basemap. I want to define a rectangular orthogonal grid, rotated clockwise
by about 13 degrees. I want to define grid cells of size, say, about 20x20

Thank you Jeff. Setting LD_LIBRARY_PATH works fine as a quick test, though
that leads me to the "ImportError: No module named pkg_resources" problem
that the other recent posters had. I'll either try setuptools or wait for
0.9.9 to come out - will it be long?

Hi all,
Just updated basemap from 0.9.4 to 0.9.8 on Mandriva Linux 2008. I also
installed basemap-data-fullres-0.9.7. I've noticed there's a couple of
recent posts about problems (on Macs) with 0.9.8, the solution being to
install setuptools until 0.9.9 comes along; the problem I have is similar

Hi, I am trying to install matplotlib 0.90.1. I have python 2.5 on a fresh

these are ok, they both import and the tests were largely successful. I

r show how to fix the script,
or I can use the script to help me track down the mpl bug, if that is
the problem.

Hi Eric
I am using matplotlib-0.90.0.
I am making 2 contourf subplots of temperature values which have similar but
not equal ranges. In subplot1 the range is 15-25; in subplot2 it is 16 to
24. I use clim, giving it the max and min values obtained from a comparison
of subplot1 and 2; i.e., I us
Sorry, I realise that my example in my original post doesn't quite make
sense. My data range is 17 to 23. I set clim to be clim([15, 25]). I then
want the colorbar limits to be the same as clim, 15 to 25. The questions
remains the same, which is how to set the range for colorbar.
Thanks, Evan
Hi
I want to set the limits of my colorbar to something different from that of
my plot. For example I have a contourf plot where I set the colour limits
to be, say:
clim([15, 25])
But I want the limits of the colorbar to be 10 and 30. I suspect this is
something to do with mappable and vmin a
