matplotlib is a pure python plotting library designed to bring publication quality plotting to python with a syntax familiar to matlab users. A lot progress towards this goal has been made since the first release of matplotlib, the library does produce high quality 2D plots. All of the plotting commands can be accessed either via a functional interface familiar to matlab users or an object oriented interface familiar to python users, and several high resolution output formats are supported.
