Re: [Matplotlib-users] vector EPS
I believe that MPL produces vector files. If you want to check by yourself I suggest that you zoom at will on an eps file. If you cannot observe rasterization artifacts it should be right. There is a rasterized option that will affect part of a plot but will leave the text and axes vectorized.

Is there any way to get around this ... hi matt, i think i know maybe what you mean: if i save a matplotlib figure as eps and then use pstoedit for further processing with xfig, the ticklabels are somehow not correctly recognized as text. as far as i understand, this is an issue with the mathtext capabilities. you can see what i do as workaround in http://www.thamnos.de/repos/sebtools/sebtools.main/sebtools.py (class 'Fig', style 'f') unfortunately, i do not recall all details any more. if i was to look into that again, i would start playing with the text.usetex parameter. i would expect this to be enough to render linear axes correctly (although not as nicely). if you have logarithmic axes, it gets more complicated as something like 10^5 IS a mathtext. i've therefore made a class MyLogFormatterMathtext which outputs the labels very ugly but as normal text. i hope that something along these lines can help you, i was using pstoedit a lot to see whether the text is recognized as text or not. good luck, sebastian.

Re: [Matplotlib-users] transData.transform on 'log' plot
The `transform` method requires that its argument is a numpy array. You got
lucky with duck typing in the non-log case, but there is an assumption in the
transformation code that it can use Numpy array functionality on whatever is passed in.
Unfortunately, the transforms code is so low-level and core to matplotlib that any
checking or coercing of the types passed in makes a significant impact on interactive
performance, so I'm reluctant to add that. The docstring does say this:
Performs the transformation on the given array of values.
Accepts a numpy array of shape (N x :attr:`input_dims`) and
returns a numpy array of shape (N x :attr:`output_dims`).
I've attached a fixed version of your script that uses Numpy arrays
rather than tuples for the points.

Re: [Matplotlib-users] vector EPS
http://matplotlib.sourceforge.net/users/usetex.html Postscript options In order to produce encapsulated postscript files that can be embedded in a new LaTeX document, the default behavior of matplotlib is to distill the output, which removes some postscript operators used by LaTeX that are illegal in an eps file. This step produces results which may be unacceptable to some users, because the text is coarsely rasterized and converted to bitmaps, which are not scalable like standard postscript, and the text is not searchable. One workaround is to to set ps.distiller.res to a higher value (perhaps 6000) in your rc settings, which will produce larger files but may look better and scale reasonably. A better workaround, which requires Poppler http://poppler.freedesktop.org/ or Xpdf http://www.foolabs.com/xpdf, can be activated by changing the ps.usedistiller rc setting to xpdf. This alternative produces postscript without rasterizing text, so it scales properly, can be edited in Adobe Illustrator, and searched text in pdf documents. fwiw, Alan Isaac -- Throughout its 18-year history, RSA Conference consistently attracts the world's best and brightest in the field, creating opportunities for Conference attendees to learn about information security's most important issues through interactions with peers, luminaries and emerging and established companies. http://p.sf.net/sfu/rsaconf-dev2dev ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users

[Matplotlib-users] Font size on an axis
Hey all,
wow, this seems like it should be an easy thing but I am not finding
answers in the gallery or searching the documentation.
How does one set the font size on ticklabels and labels for a figure?
I would expect something like plot(arange(11), xfontsize=14) to work
but I am not finding any keywords here for that. what am I missing?
this works for the labels
plot(arange(11))
ax=gca()
ax.set_xlabel('i am x', size=18)
I am trying all sorts of weird things for the ticklabels like
plot(arange(11))
ax=gca()
for val in ax.get_xticklabels():
ax.set_xticklabels(val._text, size=18)
but this must be wrong.
Thanks much,
Brian

You should not call set_text directly, instead you need to call Axis.set_ticklabels. If you want the top (right) ticks have different ticklabels than the bottom (left) ticks, that is not possible.

When the minimum value of z coincides with the lowest level, then regions with that minimum are left blank; so the lowest level is adjusted downward slightly, making the lowest contour interval include the minimum value. I understand levels can be adjusted for a better contouring, but I'm not sure whether this change needs to be visible to users. The autoleveler, initially creates following levels [0, 1.5, 3, 4.5, 6, 7.5, 9.] But due to the reason you described above, they become array([ -9.e-06, 1.5000e+00, 3.e+00, 4.5000e+00, 6.e+00, 7.5000e+00, 9.0900e+00]) And the colorbar uses the adjusted levels for labeling. But I think it may make more sense to use the initial levels (at least for the colorbar ticks). JJ, I changed my mind and decided you are correct in thinking the change should be made in contour.py. I now make the bottom boundary adjustment at the last possible time, and in such a way that it does not change the levels array at all. Therefore the colorbar never sees it, and the result of explicitly supplying a set of levels is identical to the case where those levels result from autoscaling.

Re: [Matplotlib-users] '_label_angles' attribute missing
The rotation of the ticklabels are now measured relative to the direction of the ticks. While I understand this can be confusing at first, this is kind of necessary to support axis along an arbitrary path. For example, the default rotation for the ticklabels in the top axis is 180, not 0 (but it looks like 0). So, in your case, the angle should be 190, instead of 10 (at line 117). Let me know if there is any other issue. -JJ On Thu, Jan 21, 2010 at 8:34 PM, Gökhan Sever gokhanse...@gmail.com wrote: JJ, One thing is still little mysterious. My top xticks are reversed.

[Matplotlib-users] Importing pyplot crashes python
Hi, I decided to upgrade to matoplotlib 0.99.1. I'm on Windows XP. I downloaded matplotlib-0.99.1.win32-py2.5.exe and ran it. It seemed to install. Now when I try from matplotlib import pyplot, Python crashes with one of those pythonw has encountered a problem and needs to close messages. I tried uninstalling matplotlib, and I also uninstalled SciPy and upgraded that to the latest version (0.7.1) and then reinstalled matplotlib. Still crashes. Importing numpy on its own works, as does importing matplotlib on its own. How can I fix this problem? Thanks, -- Brendan Barnwell Do not follow where the path may lead.

Re: [Matplotlib-users] Assigning k key for xscaling
Hi Gökhan, Hi list members, This is really a missing feature in matplotlib in my opinion and it's great that you took the time to make an suggestion, but I would prefer capital L for the xaxis-scaling like gnuplot although I'm not sure this is possible.
