[matplotlib-devel] default axes rect From: Jeff Whitaker - 2005-10-02 23:23:40 ```Anyone know how the default axes rectangle is set? The default width and height are apparently not the same >>> from pylab import * >>> ax=axes() >>> ax.get_position() [0.125, 0.099999999999999978, 0.77500000000000002, 0.80000000000000004] I'd like the last two numbers to be identical (say 0.8), that way I can be sure that a plot will have a certain aspect ratio if the figure dimensions have that aspect ratio. -Jeff -- Jeffrey S.

If no args are passed to axes, a subplot(111) is created. If you want to control the rectangle, just pass in the l,b,w,h args ax = axes([0.1, 0.1, 0.8, 0.8]) If you want to see how the default subplots are created, see axes.Subplot and the subplot params left : 0.125 # the left side of the subplots of the figure right : 0.9 # the right side of the subplots of the figure bottom : 0.1 # the bottom of the subplots of the figure top : 0.9 # the top of the subplots of the figure wspace : 0.2 # the amount of width reserved for blank space between subplots hspace : 0.2 # the amount of height reserved for white space between subplots JDH PS: thanks for the basemap notes -- I presented them at scipy and there appeared to be a fair amount of interest in it. ```

I want to override those defaults in basemap so that the width and height are both 0.8 (they are 0.775 and 0.8 now). That way the map will have the right aspect ratio without the user having to set the axes rect manually. I've set it up so that rcParams['subplot.params.left'] is set to 0.1 when basemap is imported (a warning is printed notifying the user that the defaults have been changed, and rcdefaults() can be used to get the old ones back). Thanks a lot for presenting that material at SciPy - I've noticed an upswing in downloads since your talk. -Jeff -- Jeffrey S.
