Note -- if you call the show() function, you will turn control over to the backend (in my case, TkAgg), and lose the ability to issue interactive commands afterwards. A solution is to use the ion() (stands for "interactive-on") function call before issuing plotting commands: >>> from pylab import * >>> ion() >>> plot([1,2,3]) [<matplotlib.lines.Line2D instance at 0x2cb60a8>] >>> # image is shown here See http://matplotlib.sourceforge.net/interactive.html for an exhaustive explanation. > Every time I run the plot([1,2,3]) I get a different ending number that > seems to vary randomly. The "[<matplotlib.lines.Line2D instance at 0x2cb60a8>]" is what the plot() function returns -- a list of instances of the Line2D class, and it tells you their locations in memory (hence the hex number starting with 0x). The hex number can be used to uniquely identify this object, as in the id(object) call. Hope this helps, Kurt -- http://mail.python.org/mailman/listinfo/python-list
