We don't have 'nosetests' as a part of Sage, but it should be possible to write a script which just executes the first two lines. I'll add that to Sage so we can run the matplotlib test suite.

Re: [Matplotlib-users] How to save text in vector images as text rather than paths?
Just to note, in Linux, one can use the pdf2ps command. I believe Windows
users can use GhostScript to convert a pdf into an eps file rather than
using Illustrator for a simple conversion process.

When you say labels, are you referring to the tick labels?
If so, near the top of your script, try:
import matplotlib
matplotlib.rcParams['axes.unicode_minus'] = False
Otherwise all tick labels are treated as unicode by default, and unicode
is rendered in the ps backend as a sequence of glyphs rather than as a
single text string.
You might also consider using matplotlib to write pdf files instead of
ps. The eps format is older and more limited in its capabilities than
pdf. You can always convert pdf to eps as a last step, if eps is what
you ultimately need. I've never used Illustrator, but I presume it can
happily import pdf and export eps.

[Matplotlib-users] progress bar?
I've been searching but coudn't find any example on how to add a
progress bar to a wxpython+matplotlib app.
I'd like my app to show a progress bar while some gridding and
contouring are being done.
this is the code I'm using (without preogress bar)

Triangulation:'linear',Multiquadric:'multiquadric',Inverse
Multiquadric:'inverse multiquadric',Gaussian:'gaussian',Linear
RBF:'linear',Cubic:'cubic',Quintic:'quintic',Thin-plate
Spline:'thin-plate'}
# check what kind of interpolation are we using
if interp == 'Natural Neighbor' or interp == 'Triangulation': #
Delaunay-based (mlab)
xi = yi = np.linspace(-1.1,1.1,ngrid)
zi = griddata(node_x,node_y,z,xi,yi,interp=funcs[interp])
else: # Radial basis functions (scipy)
ti = np.linspace(-1.1,1.1,ngrid)
xi, yi = np.meshgrid(ti, ti)
rbf = Rbf(node_x, node_y, z,
function=funcs[interp],epsilon=epsilon,smooth=smoothing)
zi = rbf(xi, yi)

Re: [Matplotlib-users] interpolation 2d: delaunay and griddata, bad results
The griddata function should be doing delaunay triangulation by default, so the result from griddata should be identical to the second plot. I see that you are using a mask for x0, y0, v0. This is unnescessary, as you really want to pass the flat arrays. I can not get a masked array from griddata. Actually, I have to pass in flat arrays to make it work at all. And the result is identical to the second plot: ui = pylab.mlab.griddata(x0.flat, y0.flat, v0.flat, xi, yi) As to whether the result is correct or not, I am not qualified to say, so I will leave that to someone else to determine.

[Matplotlib-users] zorder for individual points in a scatter plot on a Basemap
Hi,
I'm currently using a scatter plot on a Basemap and I'd like to set the
zorder of the individual points based on their temperature. The higher the
temperature, the higher the zorder. Also, i'm using a colorbar to set the
colors for the plot. Here is a snippet of my code:
x = np.array(val)
fig.sca(ax1)
lon_0 =(urcrnrlon+llcrnrlon)/2
lat_0 =(urcrnrlat+llcrnrlat)/2
m =
Basemap(llcrnrlon=llcrnrlon,llcrnrlat=llcrnrlat,urcrnrlon=urcrnrlon,
urcrnrlat=urcrnrlat,resolution='i',projection='cyl',lon_0=lon_0,lat_0=lat_0)
m.drawcoastlines()
m.drawmapboundary()
m.drawparallels(np.arange(llcrnrlat-1,urcrnrlat+1,5.))
m.drawmeridians(np.arange(llcrnrlon-1,urcrnrlon+1,5.))
m.fillcontinents(color='white',lake_color='aqua')
m.drawcountries(linewidth=1)
lons,lats = m(lon,lat)
#I can do it this way, but this screws up the colorbar
#for i in range(len(x)):
#
m.scatter(lons[i],lats[i],c=x[i],marker='o',picker=5,zorder=x[i])
m.scatter(lons,lats,c=x,marker='o',picker=5)
plt.title('Time Range: %s to %s'%(startDay.strftime(%b-%d
%H:%M),endDay.strftime(%b-%d %H:%M)))
plt.colorbar(shrink=0.5)
Is there anyway to set the zorder of the points without using the loop in
commented code? Any help would be greatly appreciated.
Thanks,
Aman

If you don't mind trying developer releases, use basemap 0.99.5 from http://www.lfd.uci.edu/~gohlke/pythonlibs/#basemap, which should work with numpy 1.4.1. Success!

[Matplotlib-users] colorbar rescaling
Hi, I hope someone can answer this colorbar related question. I have a plot, to which I am drawing a colorbar. The standard colorbar ranges from the values -1 (blue) over 0 (green) to e.g. 1(red). So far so good. But now I want to change the colorbar that it shows only the colors between 0 and 1. What I mean is: the colorbar should start at value 0 (with green) and go to 1(red), and leave the original plot unchanged. I ad some example code below to make it more clear. In the example plot created, only the values between 0 and 1 are interesting and should be shown in the colorbar, but not -1 (blue). But I want the original plot unchanged! If anyone has an idea that would be great.

Re: [Matplotlib-users] Symbol not found
It didn't work. But I may have misunderstood your instructions. Here's the output from compiling matplotlib: http://pastebin.org/363870 Here's what I did. Set export CC=gcc-4.2 Set export MACOSX_DEPLOYMENT_TARGET=10.5 Downloaded and compiled libpng-1.4.3 Downloaded and compiled libfreetype-2.3.12 Downloaded matplotlib-0.99.3 Modified src/_png.cpp in matplotlib Replaced setupext.py with your version. sudo python setup.py build sudo python setup.py install Any obvious mistakes?

I remember that make.osx is intended for binary distributable generation, and therefore it links statically. I want to propose a different solution here. Would you please modify first your matplotlib setupext.py in the following way. We'll attemt a build without make.osx and fetch etc., but a real distutil build with dynamic linking :-) !: On the line with 'darwin' : [], add: 'darwin' : ['/usr/local'], and maybe also '/usr/X11/lib' or '/usr/X11' and let the /lib suffix alone, but I think as you installed pkg-config, it could maybe work also out of the box. For me, I were not aware of pkg-config for OS X, so I still don't have it :-). If you are not sure, simply try to run pkg-config in the console, by tab expansion, if it finds it, it's installed. I also attach the modified files for your convenience, but you should use diff because I built that time 0.99.1.2, and something may have changed by that. Then, please compile (if you did not already do that), libpng 1.4 (not 1.2!) and libfreetype2 from the official sources. Always use the following environment variables: export CC=gcc-4.2 (To not use 4.0 occasionally) export MACOSX_DEPLOYMENT_TARGET=10.5 (To avoid certain warnings which are quite annoying during build. If you attemt to use py2app for deployment on 10.3 or 10.4 you should modify of course.) It is important that you compile *all* your software which is incorporated with the same variables. Well, at least I by accident one time set _TARGET to another value after ./configure, and it refused to compile then. So, feel free to experiment, but please document properly and, most important, tell us the results! I'm still in the ascending branch of my OS X learning curve. Maybe now it's the right moment to compile Python (1.6.5, I think not 1.7) and then numpy again with this settings. For Python, use ./configure --enable-framework Then compile libfreetype2. Compile libpng 1.4 or whatever. Now it's time to compile matplotlib itself. Just use the usual flags, and, for me, it worked like a charm. But one modification has to be made: matplotlib isn't compatible with libpng 1.4 from the beginning, please add the following lines to src/_png.cpp: #define png_infopp_NULL (png_infopp)NULL #define int_p_NULL (int*)NULL Somewhere before the actual code, it doesn't matter where, but after the #include png.cpp of course. I also attach the file, same applies, run diff before. It's my obligation to provide a proper matplotlib patch for this issue, but for now please patch by hand. There are several reasons why to compile Python yourself: It will use the new Tcl/Tk, which is much more beautiful than the old one. It will compile with the compatible flags. Well that's it I think. If you intend to use PIL btw, you have to compile Python yourself. Now you should be done. If you run into some problems, please tell us.

Re: [Matplotlib-users] colorbar rescaling
2010/6/28 Alexander Dietz alexanderdie...@googlemail.com: I have a plot, to which I am drawing a colorbar. The standard colorbar ranges from the values -1 (blue) over 0 (green) to e.g. 1(red). So far so good. But now I want to change the colorbar that it shows only the colors between 0 and 1. What I mean is: the colorbar should start at value 0 (with green) and go to 1(red), and leave the original plot unchanged. Ah, it wasn't that easy (for me).

[Matplotlib-users] abort trap
I've been having some trouble with compiling matplotlib on Snow Leopard. I managed to get rid of all my old problems by recompiling everything with gcc-4.2. But now when I import matplotlib.pyplot I get an Abort trap message and python quits.

Re: [Matplotlib-users] abort trap
I tried again by compiling version 2.4.11 of freetype instead of the latest and recompiling matplotlib with that and now I get the following less severe error: Traceback (most recent call last): File stdin, line 1, in module File /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/pyplot.py, line 6, in module from matplotlib.figure import Figure, figaspect File /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/figure.py, line 18, in module from axes import Axes, SubplotBase, subplot_class_factory File /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/axes.py, line 12, in module import matplotlib.axis as maxis File /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/axis.py, line 10, in module import matplotlib.font_manager as font_manager File /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/font_manager.py, line 52, in module from matplotlib import ft2font ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/ft2font.so, 2): Library not loaded: /usr/local/lib/libfreetype.6.dylib Referenced from: /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/ft2font.so Reason: Incompatible library version: ft2font.so requires version 11.0.0 or later, but libfreetype.6.dylib provides version 10.0.0 On Mon, Jun 28, 2010 at 5:43 PM, Ranjit Chacko rjcha...@gmail.com wrote: I've been having some trouble with compiling matplotlib on Snow Leopard.
