intro

matplotlib tries to make easy things easy and hard things possible. You can generate plots, histograms, power spectra, bar charts, errorcharts, scatterplots, etc, with just a few lines of code. For a sampling, see the screenshots, thumbnail gallery, and -examples directory

For example, using "ipython --pylab" to provide an interactive environment, to generate 10,000 gaussian random numbers and plot a histogram with 100 bins, you simply need to type

intro

For the power user, you have full control of line styles, font properties, axes properties, etc, via an object oriented interface - or via a set of functions familiar to MATLAB users. - The pylab mode provides all of the pyplot plotting - functions listed below, as well as non-plotting functions from - numpy and - matplotlib.mlab.
