I'm not sure if the default formatter needs to be changed. However, you may try import matplotlib.ticker as ticker formatter=ticker.LogFormatterMathtext() colorbar(format=formatter) which will render colorbar ticklabels with mathtext mode.

On Debian/Ubuntu-like systems with apt-get, you can get all of the development headers required for matplotlib in one fell swoop with: sudo apt-get build-dep python-matplotlib Mike Mauro Cavalcanti wrote: > As I posted before, I ran across precisely these same errors when > upgrading my Ubuntu box and the Python interpreter.

Could you try to use figure() instead of Figure()? That often creates a
mess on my side.
Or should one use Figure() in the 'Artist's style? I am still importing
pyplot as plt, and in that case, I have to use figure(), otherwise
things don't work.
I also had the feeling of a leak and am currently doing this without
much 'leaking': :)
fig = plt.figure()
ax = fig.add_subplot(111)
im = ax.imshow(nData)
cb = plt.colorbar(im)
ax.set_title(bname + ', ' + mode)
fig.savefig(filename + '.equal.png')
plt.close(fig)
I think, the plt.close(fig) was quite important in my case.
Give it a try!
Best regards,
Michael

As I posted before, I ran across precisely these same errors when upgrading my Ubuntu box and the Python interpreter. You will need to install other dependencies as the installation log shows (gtk-2.0+, pygtk), including its development versions. And yes, distributing a packaged Python application which uses Matplotlib (either for Linux or Windows) is *not* an easy and simple matter. But with patience, it is possible.

Does forcibly casting the path to a string resolve the problem? i.e.

Assuming that the matplotlibrc file being read is in mpl-data, here is the relevant section: ### FONT # # font properties used by text.Text. See # http://matplotlib.sourceforge.net/api/font_manager_api.html for more # information on font properties. The 6 font properties used for font # matching are given below with their default values. # # The font.family property has five values: 'serif' (e.g. Times), # 'sans-serif' (e.g. Helvetica), 'cursive' (e.g. Zapf-Chancery), # 'fantasy' (e.g. Western), and 'monospace' (e.g. Courier). Each of # these font families has a default list of font names in decreasing # order of priority associated with them. # # The font.style property has three values: normal (or roman), italic # or oblique. The oblique style will be used for italic, if it is not # present. # # The font.variant property has two values: normal or small-caps. For # TrueType fonts, which are scalable fonts, small-caps is equivalent # to using a font size of 'smaller', or about 83% of the current font # size. # # The font.weight property has effectively 13 values: normal, bold, # bolder, lighter, 100, 200, 300, ..., 900. Normal is the same as # 400, and bold is 700. bolder and lighter are relative values with # respect to the current weight. # # The font.stretch property has 11 values: ultra-condensed, # extra-condensed, condensed, semi-condensed, normal, semi-expanded, # expanded, extra-expanded, ultra-expanded, wider, and narrower. This # property is not currently implemented. # # The font.size property is the default font size for text, given in pts. # 12pt is the standard value. # #font.family : sans-serif #font.style : normal #font.variant : normal #font.weight : medium #font.stretch : normal # note that font.size controls default text sizes. To configure # special text sizes tick labels, axes, labels, title, etc, see the rc # settings for axes and ticks. Special text sizes can be defined # relative to font.size, using the following values: xx-small, x-small, # small, medium, large, x-large, xx-large, larger, or smaller #font.size : 12.0 #font.serif : Bitstream Vera Serif, New Century Schoolbook, Century Schoolbook L, Utopia, ITC Bookman, Bookman, Nimbus Roman No9 L, Times New Roman, Times, Palatino, Charter, serif #font.sans-serif : Bitstream Vera Sans, Lucida Grande, Verdana, Geneva, Lucid, Arial, Helvetica, Avant Garde, sans-serif #font.cursive : Apple Chancery, Textile, Zapf Chancery, Sand, cursive #font.fantasy : Comic Sans MS, Chicago, Charcoal, Impact, Western, fantasy #font.monospace : Bitstream Vera Sans Mono, Andale Mono, Nimbus Mono L, Courier New, Courier, Fixed, Terminal, monospace ### TEXT # text properties used by text.Text. See # http://matplotlib.sourceforge.net/api/artist_api.html#module-matplotlib.textfor more # information on text properties #text.color : black ### LaTeX customizations. See http://www.scipy.org/Wiki/Cookbook/Matplotlib/UsingTex #text.usetex : False # use latex for all text handling. The following fonts # are supported through the usual rc parameter settings: # new century schoolbook, bookman, times, palatino, # zapf chancery, charter, serif, sans-serif, helvetica, # avant garde, courier, monospace, computer modern roman, # computer modern sans serif, computer modern typewriter # If another font is desired which can loaded using the # LaTeX \usepackage command, please inquire at the # matplotlib mailing list #text.latex.unicode : False # use "ucs" and "inputenc" LaTeX packages for handling # unicode strings. #text.latex.preamble : # IMPROPER USE OF THIS FEATURE WILL LEAD TO LATEX FAILURES # AND IS THEREFORE UNSUPPORTED. PLEASE DO NOT ASK FOR HELP # IF THIS FEATURE DOES NOT DO WHAT YOU EXPECT IT TO. # preamble is a comma separated list of LaTeX statements # that are included in the LaTeX document preamble. # An example: # text.latex.preamble : \usepackage{bm},\usepackage{euler} # The following packages are always loaded with usetex, so # beware of package collisions: color, geometry, graphicx, # type1cm, textcomp. Adobe Postscript (PSSNFS) font packages # may also be loaded, depending on your font settings #text.dvipnghack : None # some versions of dvipng don't handle alpha # channel properly. Use True to correct # and flush ~/.matplotlib/tex.cache # before testing and False to force # correction off.

One might see that error if the path to the font being used contains non-ascii characters (the "basename" variable in the last frame of the stack in the stacktrace). Is that possible? We may need to implement the same workaround we use for image files for loading fonts (which is to open the file with Python and pass a file handle to C++ rather than passing a string that may contain Unicode, which is difficult to handle in cross-platform way from C/C++).

I'm not able to reproduce that here, with either SVN or 0.99.1.2. Do you have any font-related or mathtext-related settings in your matplotlibrc?

It makes less efford when one can rely on the automatic ticking mechanism and when one has access to the axis (with i) instances. It is: To obtain math-formatted number output: >>> formatter = matplotlib.ticker.FormatStrFormatter('$%g$') >>> axes.xaxis.set_major_formatter(formatter) The most important is that one has no longer to set the tick locations manually. For exponential ticks, I would propose (but it's untested): >>> def exp_fmt(loc): exponent = numpy.round(numpy.log10(loc)) return '$10^%d$' % exponent >>> formatter = matplotlib.ticker.FuncFormatter(exp_fmt) >>> # And so on. Note that using r'$\mathbf{%g}$' makes, for me, no difference. It may be that one needs matplotlib.rc('text', usetex = True) to make also numbers bold by \mathbf{}, but iirc, also in LaTeX numbers are always plain, also in \mathbf{}. \boldmath$$ may be an exception from this rule. fwiw, Friedrich P.S.: I cannot test usetex = True at the moment, because I end up with the error 'Could not obtain dvipng version'. |

I'm not sure I understand the question. Can you provide a standalone script that illustrates the problem, or at least a picture?

The problem is really that the window is too small, the text is too
large, and/or the axes is too large within the figure.
Try one or more of the following:
Replace the values for win.set_default_size to something larger, eg.
win.set_default_size(800,600)
Replace the fig.add_subplot call with a fig.add_axes call that
explicitly specifies the axes position:
ax = fig.add_axes((0.2, 0.2, 0.6, 0.6))
Reduce the font size by adding the following to the top:
from matplotlib import rcParams
rcParams['font.size'] = 4
Reduce the dpi of the plot:
fig = Figure(figsize=(5,4), dpi=60)
Cheers,
Mike

It's not currently possible, but could be added by defining another directive option and passing that to the savefig call within the plot directive. If you're not able to do this yourself, would you mind filing a bug and linking to it here so it doesn't get forgotten? Mike Thomas Robitaille wrote: > Hello, > > I am currently using the sphinxext module to write documentation that includes automatically generated plots. I was wondering if there is a way to override the default savefig behavior for this - for example, I would like all the plots for the documentation to have the bbox_inches='tight' option to avoid any unnecessary whitespace. Is this something that can be done? > > Thanks, > > Thomas > > ------------------------------------------------------------------------------ > Download Intel® Parallel Studio Eval > Try the new software tools for yourself.

It looks like the end of the traceback -- where the actual exception is named -- is missing. Can you repost it in its entirety? Mike william ratcliff wrote: > Hi!

It looks like you are need to install libfreetype6-dev. Any time you see missing .h files in your output, it means you need to install the development headers for that package. Darren |

My goal is to just get the lastest svn version of matplotlib, or, if
not that, just the 0.99 version, up and working on my Linux (Intrepid
Ibex) computer. I checked it matplotlib out from svn fine, and then,
as per the webpage, did:
> cd matplotlib
> python setup.py install
and that resulted in a very large amount of errors. I'll post them at
the bottom of this message, since there are many lines.
I previously had 0.98.x installed, via the Ubuntu repositories, but I
have uninstalled it. My version is:
Linux ubuntu 2.6.27-7-generic #1 SMP Fri Oct 24 06:40:41 UTC 2008
x86_64 GNU/Linux
Any help is appreciated. Thank you,
Che

Hi! I am using matplotlib 0.99.0 under windows xp. I tried the following: ax.text(.96,.80,r'$P \perp Q$',fontsize=18,horizontalalignment='right',verticalalignment='top',transform=ax.transAxes,color='black') and get the following error: (However, in figure labels, symbols using mathtext, such as theta seem to work fine...) Thanks, William TypeError: cannot return std::string from Unicode object File "C:\mytripleaxisproject\trunk\eclipse\src\utilities\bfo_film_fig2.py", line 301, in <module> film110() File

Waiting for some updates till I hear a resolution. The annoying part is when I created a plot using specified width and height Qt4Agg doesn't follow these dimensions as in this case and resulting savefig(file.pdf) produces wrongly sized file unless I manually extend the figure area and re-issue a savefig afterwards. -- Gökhan |
