Graphical Representations of Data

Over the years many different plotting modules and packages have been developed for Python. For most of that time there was no clear favorite package, but recently matplotlib has become the most widely used. Nevertheless, many of the others are still available and may suit your tastes or needs better. Some of these are interfaces to existing plotting libraries while others are Python-centered new implementations.

Image Processing and Analysis

  • The PIL Toolkit provides a very powerful set of tools for manipulating images. Documentation

  • PyQtGraph is a pure-python graphics library built on PyQt4 and numpy. It is intended for use in mathematics / scientific / engineering applications. The library provides widgets and graphicsItems for displaying / analyzing live image data (including 16-bit) as well as translate/scale/rotatable region-of-interest widgets for interactively slicing numpy arrays. The library is very fast due to its heavy leverage of numpy and Qt's graphicsView framework.

The library is very fast due to its heavy leverage of numpy and Qt's graphicsView framework. Major features: 1) a feature-rich plotting system, and 2) an image display system with translate/scale/rotatable region-of-interest widgets.

  • pyla is a set of pure-python 3 (3.x) libraries for 2D/3D plotting using Gnuplot, linear algebra (vector-matrix) operation, ode (ordinary differential equation) solvers, optimization and nonlinear algebraic equation solvers. It is in alpha release and its gplot library has been released. pyla-gplot is a very simple yet powerful library very similar to Gnuplot.py but works under python 3.x and does not require Numpy.

  • cartesius is a small library for 2d coordinate system images.

Also of Note

  • There is an interface to the OpenGL library called PyOpenGL that can be used to write sophisticated visualization tools from scratch.

  • The FXPy bindings to the FOX GUI library support OpenGL, so might be a good starting point for new applications.
