For some reason, downloading this file fails quite often. Perhaps it should be distributed using the same sf.net download mechanism as the software itself? Try using some software that knows how to resume interrupted downloads. E.g., run curl -O -C - http://matplotlib.sourceforge.net/users_guide_0.87.1.pdf as many times as needed to get the whole file. > http://www.scipy.org/Cookbook/Matplotlib/BarCharts > shows how to setup labels for a bar chart - but it would be great if > there was a line-by-line explanation of what each step means I think the best way to understand the examples is to start up "ipython -pylab", copy/paste the examples line by line, inspect the resulting objects, get help on the mysterious functions (e.g. type ?gca in ipython to find out what gca does), form hypotheses on what the various steps do, and test the hypotheses with experiments. > setting line widths, font sizes, bar colours etc bar returns a list of Rectangle objects: In [19]: bar([1,2,3], [4,5,6]) Out[19]: [<matplotlib.patches.Rectangle instance at 0x2aaab2f33290>, <matplotlib.patches.Rectangle instance at 0x2aaab2f33200>, <matplotlib.patches.Rectangle instance at 0x2aaab2f33248>] Capture these objects and use getp and setp on them: In [20]: recs = _ In [21]: getp(recs[0]) ... In [22]: setp(recs[0], 'facecolor') facecolor: any matplotlib color - see help(colors) In [23]: help(colors) ... In [24]: setp(recs[0], 'facecolor', 'red') Out[24]: [None] For font sizes you need to get a handle to the relevant Text objects. For axis texts, look at the object returned by gca(): In [36]: setp(getp(gca(), 'yticklabels'), 'fontsize', 18) Most of these settings are easier to do by using keyword arguments of the initial commands: In [38]: bar([1,2,3], [4,5,6], color=['red', 'green', 'blue']) But the getp/setp method is great for tuning the image interactively and learning about what can be customized. -- Jouni ------------------------------------------------------------------------- Using Tomcat but need to do more?
