When looking, e.g. at axes.py, I see 3 different arguments passed to numpy astype()/array()/zero() and friends: x = np.asarray(x).astype(np.float32) x = np.zeros( x, np.float_ ) x = np.ones((col,), float) Is there a preferred one to stick to ?! Manuel
Hi, I'm trying to make a Skew-T LogP plot, an important plot in meteorology, using matplotlib (mainly to help convert people away from much more horrible solutions). You can see one here: http://www.rap.ucar.edu/weather/upper/oun.gif and more cartoonish: http://www.srh.noaa.gov/oun/images/figure6.gif (Pay attention only to the lower part with the bold red and green lines). I'm pretty sure matplotlib can't currently do this, but it shouldn't be too hard. The crux of the plot is that you plot temperature as a function of pressure, with pressure reversed and logarithmically spaced on the Y-axis (ie. high pressure at the bottom) and temperature plotted skewed along the X axis. That is, the lines of constant temperature intersect the bottom at 45 degree angles. I know matplotlib can do log axes, so how hard would it be for me to create a transform that can handle the 45 degree skew of the temperature? Thanks, Ryan -- Ryan May Graduate Research Assistant School of Meteorology University of Oklahoma
Hi, I'm using matplotlib on osx leopard (compiled with gcc-4.3) and if I try to render a simple plot I see lots of these errors: python(58290) malloc: *** error for object 0xa06026d8: Non-aligned pointer being freed *** set a breakpoint in malloc_error_break to debug I get the following backtrace with gdb: Breakpoint 1, 0x94458131 in malloc_error_break () (gdb) bt #0 0x94458131 in malloc_error_break () #1 0x9445311f in szone_error () #2 0x94377743 in szone_free () #3 0x943775ad in free () #4 0x0175c305 in std::string::assign (this=0xbfffa5e0, __str=@0xbfffa5dc) at bits/basic_string.h:236 #5 0x018e6b00 in FT2Font::set_text (this=0x34544d0, args=@0x17a3674, kwargs=@0xbfffa674) at src/ft2font.cpp:927 #6 0x018ef04c in Py::PythonExtension<FT2Font>::method_keyword_call_handler (_self_and_name_tuple=0x35819e0, _args=0x3581a30, _keywords=0x358bd20) at Extensions.hxx:671 #7 0x001e0211 in PyCFunction_Call (func=0x3581c88, arg=0x3581a30, kw=0x358bd20) at Objects/methodobject.c:77 #8 0x001a3b51 in PyObject_Call (func=0x3581c88, arg=0x3581a30, kw=0x358bd20) at Objects/abstract.c:1861 #9 0x00239cc0 in PyEval_EvalFrameEx (f=0x3453370, throwflag=0) at Python/ceval.c:3784 #10 0x0023d3b5 in PyEval_EvalCodeEx (co=0x1df2848, globals=0x1de0ae0, locals=0x0, args=0xb753e4, argcount=3, kws=0xb753f0, kwcount=1, defs=0x0, defcount=0, closure=0x0) at Python/ceval.c:2836 #11 0x0023bd1d in PyEval_EvalFrameEx (f=0xb75210, throwflag=0) at Python/ceval.c:3669 #12 0x0023d3b5 in PyEval_EvalCodeEx (co=0x1b50068, globals=0x18ba930, locals=0x0, args=0x3452914, argcount=2, kws=0x345291c, kwcount=0, defs=0x0, defcount=0, closure=0x0) at Python/ceval.c:2836 #13 0x0023bd1d in PyEval_EvalFrameEx (f=0x34527a0, throwflag=0) at Python/ceval.c:3669 #14 0x0023d3b5 in PyEval_EvalCodeEx (co=0x1b500f8, globals=0x18ba930, locals=0x0, args=0x35819c4, argcount=2, kws=0x0, kwcount=0, defs=0x0, defcount=0, closure=0x0) at Python/ceval.c:2836 #15 0x001c944e in function_call (func=0x1b583f0, arg=0x35819b8, kw=0x0) at Objects/funcobject.c:517 #16 0x001a3b51 in PyObject_Call (func=0x1b583f0, arg=0x35819b8, kw=0x0) at Objects/abstract.c:1861 #17 0x001abc4d in instancemethod_call (func=0x1b583f0, arg=0x35819b8, kw=0x0) at Objects/classobject.c:2519 ... so it seems to come from somewhere within matplotlib. It doesn't seem to be a major issue, since the program continues fine, and the plot is rendered correctly. Any ideas on how to fix it? thanks
Hi, John. With the change, "fig = figure(figsize=(w, h))" properly creates a figure window with a correctly-sized canvas, but "fig.set_size_inches((w, h), forward=True)" raises AttributeError: 'FigureCanvasWxAgg' object has no attribute 'SetSizeFunc' in FigureManagerWx.resize. Previously, the SetInitialSize called by FigureFrameWx.__init__ and FigureManagerWx.resize was an attribute of the canvas, but the new code makes SetSizeFunc an attribute of the frame instead. FigureManagerWx.resize was still looking under the canvas. Would you please look over the attached patch? During FigureCanvasWx.__init__, it connects FigureCanvasWx.SetInitialSize to SetBestFittingSize or do_nothing if it isn't already inherited from wx.Panel. FigureFrameWx.__init__ and FigureManagerWx.resize just call FigureCanvasWx.SetInitialSize.

OK, I committed a change to svn using: def do_nothing(*args, **kwargs): warnings.warn('could not find a SetSizeFunc for backend_wx; please report your wxpython version=%s to the matplotlib developers list'%backend_version) pass # try to find the set size func across wx versions self.SetSizeFunc = getattr(self.canvas, 'SetInitialSize', getattr(self.canvas, 'SetBestFittingSize', do_nothing)) self.SetSizeFunc(wx.Size(fig.bbox.width, fig.bbox.height)) Could you guys test from svn on your respective wx versions and/or check that the logic looks correct here? Thanks, JDH

is actually huge, and ipython (how come it is called?) crashes, but
after CTRL-C I get:

Just a quick note that latex builds appear broken, and the error
message suggests it is a math problem, perhaps caused by the new
symbol table. First error is:
! LaTeX Error: Command \Cap already defined.
Or name \end... illegal, see p.192 of the manual.

I have already urged Stefan to give one about the numpy documentation editor http://sd-2116.dedibox.fr/pydocweb/wiki/Front%20Page/ Maybe we could combine two talks taking half the time of a full talk, with Stefan talking about the webapp, and someone from MPL talking about this. It would make a great, consistent, view on the current documentation efforts in scientific Python, and I bet people would be interested, maybe to bring the ideas back home on their own projects. Of course, I am speaking on a personal basis, and I can't speak for the rest of the organizing committee, but this sounds very nice. Cheers, Gaël
Looks like a nice solution to me. I don't use pie charts much myself, so I'll give it some time to see if there are any dissenters. If none, I'll go ahead and commit this to SVN. Thanks!

Hello, Pie charts are very useful, but when wedges labels are too long, the label text overlaps the pie wedge, resulting in a poor readability (see the attached file 'before_patch.pdf'). I propose to modify the file 'axes.py' in method 'pie' by replacing: xt = x + labeldistance*radius*math.cos(thetam) yt = y + labeldistance*radius*math.sin(thetam) t = self.text(xt, yt, label, size=rcParams['xtick.labelsize'], horizontalalignment='center', verticalalignment='center') texts.append(t) By: xt = x + labeldistance*radius*math.cos(thetam) yt = y + labeldistance*radius*math.sin(thetam) label_alignment = xt > 0 and 'left' or 'right' t = self.text(xt, yt, label, size=rcParams['xtick.labelsize'], horizontalalignment=label_alignment, verticalalignment='center') texts.append(t) Only 2 lines changed ;-) This way, labels are right aligned when placed at the left of the pie, and left aligned when placed on the right of the pie (instead of being always centered). See the attached file 'after_patch.pdf' for an example. I also give an example in the example.py file. Do you agree to commit that to the trunk? Thanks for making matplotlib, Benoit Hirbec Garden

I considered adding a parameter to the "math" directive to select the fontset, but then realized that wouldn't work for LaTeX (where *real* TeX is used to render the math). I thought it best to have reasonable consistency between the HTML and PDF versions of the docs, so opted for "cm" as the default. > * why do you hardcode the dpi to be 120 -- is that just a stylistic > choice? It seemed to look the best inlined in HTML on my browser with my fonts. Totally subjective choice. For people with different monitor resolutions, font sizes etc. that obviously doesn't work. But that's more a limitation of HTML (or the HTML that Sphinx currently generates) than anything else. Note also that the inline math images are not baseline-adjusted. For that, we need to get a proper baseline out of mathtext, which currently isn't possible. > BTW, in semi-related news, it appears sphinx (at least my > version) ignores the scale on the image directives, which is why the > html images appear large and the PDF ones appear small.

I consider that somewhat of a work in progress. It was important (to me at least) to have them somewhat sorted into categories, rather than just a jumbled or alphabetized list, but I still think they could be ordered better, and categorized at a finer level to pick things out faster. (See the "Comprehensive LaTeX Symbol List" for a reasonable way to do this). All that just takes busy work -- the infrastructure is already there. Another shortcoming is that the table is automatically "chunked" into 20 rows, since otherwise LaTeX will create a table that extends beyond the bottom of the page. But the chunking makes things look much less neat and is totally arbitrary. Finer-grained categories would be a good way around this. > I am eagerly > studying this sphinxext stuff -- very powerful.

It would be great to have something like a Sphinx/Documentation BoF to share our experiences thus far, or perhaps a lightning talk (which at SciPy are 10 minutes) to outline what matplotlib has done wrt documentation. If Darren were going, he'd be ideal to give that talk, but I could probably manage as well.

I'm curious about a couple of things in the mathpng func: * why do you hardcode the math font to be 'cm'? * why do you hardcode the dpi to be 120 -- is that just a stylistic choice? BTW, in semi-related news, it appears sphinx (at least my version) ignores the scale on the image directives, which is why the html images appear large and the PDF ones appear small. This is odd, because on my system rst2html respects the scale directive so it appears to be a buglet. Very nice work on the auto-generated symbol tables, btw. I am eagerly studying this sphinxext stuff -- very powerful. You know, Stefan called for a sphinx presentation the other day for scipy 08, and I think this kind of stuff would make a great talk if you are planning on attending. JDH
Ok. I think I have that worked out -- would you mind testing on
docutils 0.4? (I don't think I broke anything that wasn't already
broken...)
Cheers,
Mike

Ah. I've got 0.5. I was hoping I wouldn't have to do that crazy
backward compatibility stuff that mathpng.py does, but it looks like
I'll have to to support 0.4. I'll look into this.

That did it, I'll let you know if I see anything else. What version
of docutils are you on? Now I am using docutils-0.4-py2.4.egg
getting:

It's related to my recently updating pyparsing.py... It seems that it isn't Python 2.4 compatible anymore. I'd like to workaround the definiciences in the new pyparsing.py if I can (rather than simply revert) as the error messages are much more specific with the new version. I have submitted a workaround to this specific problem. Can you please let me know if it resolves your issue?

Actually I mistyped earlier; I was using image_demo from pylab_examples. In any case, an svn up fixed the problem. Strangely enough, reverting back to the revision that was originally raising errors didn't bring the errors back. I must have been running a cached version of one of the files.
