Matplotlib

matplotlib is a pure python 2D plotting library with a Matlab® syntax which produces publication quality figures using in a variety of hardcopy formats (PNG, JPG, TIFF, PS) and interactive GUI environments (WX, GTK) across platforms. matplotlib can be used in python scripts, interactively from the python shell (ala matlab or mathematica), in web application servers generating dynamic charts, or embedded in GTK or WX applications; see backends.

matplotlib trys 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 example, to make a histogram of data in x, you simply need to type

  >>> hist(x, 100)   # use 100 bins
  
For the power user, you have full control of line styles, font properties, axes properties, etc, via an object oriented interface or via a handle graphics interface familiar to matlab users. A summary of the goals of matplotlib and the progress so far can be found here.

The existing plotting commands have a high degree of Matlab® compatibility.
