What's new in matplotlib 0.51 Tkinter backend Todd Miller has written a Tkinter backend. This is a significant step forward, because now matplotlib works out of the box with any python + numeric. The Tkinter backend works interactively from any python shell - see the interactive documentation. Also, because TkAgg uses the agg backend for rendering, it has all of the features of agg, including fast antialiased rendering, freetype2, alpha blending, mathtext, and so on. See http://matplotlib.sf.net/backends.html#TkAgg. To use the TkAgg backend, you must launch your scripts in interactive mode > python -i myscript.py -dTkAgg otherwise they'll just pop up and disappear. freetype2 support added for agg backend With freetype2, agg now renders fonts nicely even at very small raster sizes. math text matplotlib now ships with the BaKoMa TeX Computer Modern fonts, and displays math text using TeX expressions. See screenshot http://matplotlib.sf.net/screenshots.html#mathtext_demo and the mathtext documentation http://matplotlib.sf.net/matplotlib.mathtext.html for usage information. Currently available on GTK, Agg, TkAgg and GTKAgg. If you build matplotlib yourself, you need to edit setup.py and set BUILD_FT2FONT configuration file A configuration file is placed in your install path (distutils.sysconfig.PREFIX + 'share/matplotlib'). This determines many of the default figure properties: the default backend, line properties, text properties, colors, and more. See http://matplotlib.sf.net/.matplotlibrc for an example configuration file and details. Place this in your home dir (linux and friends), or edit in the install path (windows). numarray support Todd Miller has provided a numerix module http://matplotlib.sf.net/matplotlib.numerix.html which allows you to choose between Numeric of numarray. You can set Numeric or numarray in your matplotlibrc file, with an environment variable, or from the prompt. See the numerix module for more information and numarray issues http://matplotlib.sf.net/NUMARRAY_ISSUES for a summary of known issues in using numarray. data clipping off by default Data clipping, as opposed to viewport clipping, is turned off by default. You can change the default behavior in .matplotlibrc or set it to be true when needed as in examples/stock_demo.py kwargs in plot commands The plot commands now take kwargs that are can be used to set line properties (any property that has a set_* method). You can use this to set a line label (for auto legends), linewidth, anitialising, marker face color, etc. Here is an example: plot([1,2,3], [1,2,3], 'go-', label='line 1', linewidth=2) plot([1,2,3], [1,4,9], 'rs', label='line 2') axis([0, 4, 0, 10]) legend() Bugfixes and minor improvements * GTK : fixed a subplot selection GUI bug specific to python2.2 * GTK : fixed a text layout bug * ALL : Fixed a multiple column subplot layout bug * PS : Fixed an afm parser - thanks Dominique * Agg : Agg now respects antialiased=False Download: http://sourceforge.net/project/showfiles.php?group_id=80706&package_id=82474&release_id=221304 |
