From: John Nagle on 15 Sep 2009 13:25 I'm looking for something that can draw simple bar and pie charts in Python. I'm trying to find a Python package, not a wrapper for some C library, as this has to run on both Windows and Linux and version clashes are a problem. Here's the list from the Python wiki at "http://wiki.python.org/moin/NumericAndScientific/Plotting". Almost all the options are really wrappers for some other package in C/C++. * Matplotlib -- wrapper for Antigrain, written in C/C++ * Veusz -- requires PyQt from http://www.riverbankcomputing.co.uk/pyqt, which is in C/C++ * Chaco -- requires binaries for Enthought Tool Suite * ScientificPython - uses mix of C, C++, and FORTRAN. * Gnuplot module -- wrapper for GNUPLOT * plot_wrap - wrapper for GNU plotutils * BLT - "tcltk.com" link goes to a domain squatter site. * PyQT - wrapper for Qwt C++ library * DISLIN - interface to C++ DISLIN system * Mayavi - interface to Mayavai2, standalone program * gdmodule GD - python wrapper for the GD library. * Gist - wrapper for gist graphics library * pgplot - Wrapper for pgplot. * Py-OpenDX - wrapper for IBM Data Explorer * VTK - wrapper for VTK in C++ * RPy - wrapper for R programming lnaguage * PyX - wrapper for Tex. * Biggles - wrapper for C++ module * Pychart - 100% Python, but last updated 21-Dec-2005. * PyNGL - uses PyNIO, which is in C * pygooglechart - Python interface to the Google Chart LookinAPI, only works in browser So, for pure Python, Pychart is it. I'll have to try it and see if it still works. John Nagle

This thing just creates PostScript, then pumps it through GhostScript (anybody remember that?) to get other formats. And does the documentation say that? Only in the FAQ section. Grrr. There doesn't seem to be any pure Python chart module at all. Just wrappers. John Nagle

The value of this variable must be one of the following strings. ps: eps: Encapsulated PostScript. This is the default. pdf: Adobe Page Description Format, or PDF. pdf-uncompressed: PDF without compression. This option should be used for a debugging purpose only. png: PNG graphics. You need to have ghostscript (gs) installed to use this option, because PyChart internally calls ghostscript to convert PostScript to PNG. </excerpt> Looks like it will directly create pdf files, not sure if that will for you. Hope this helps. ~Ethan~ |
