My intuition is exactly like that. After importing matplotlib.pyplt as plt, plt.figure creates an object that acts as canvas, and then I plot various things (hist, is one example), and when I am satisfied, I plt.savefig(path) or plt.show() the figure. The figures are saved in the directory where the script is run (its cwd, or current working directory, on linux). I have also used hist without having a figure, but that was because I wanted the histogram data, i.e., the numbers of data points in the different bins. That script used plt.hist to generate such data, and later (after running fig = plt.figure) used plt.plot to plot parts of the data in different ways. By the way, matplotlib.pyplot is one way of using matplotlib. There is also the "object oriented interface", which I have never used. / johan ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
