* What is this package?
PyChart is a Python library for creating professional quality PS, PDF,
PNG, or SVG charts. It supports line plots, bar plots, range-fill
plots, and pie charts. Because it is based on Python, you can make
the full use of Python's scripting power.
The PyChart home page is at
http://www.hpl.hp.com/personal/Yasushi_Saito/pychart
* What you need
You need Python (http://www.python.org) version 2.2 or later (on
Debian GNU/Linux, you need, python-xml package as well). You also need
Ghostscript (http://www.cs.wisc.edu/~ghost/) to produce PNG
files.
Pychart used to require Ghostscript during PS and PDF
generation to obtain font metric information, but that's no
longer the case.
* Platforms supported
In theory, PyChart works on any platform with Python. In practice,
I've run PyChart on Linux and Win2000.
* Installation
Become a root and do:
# python setup.py install
Or, you can set PYTHONPATH environment variable before you start
Python. For example (in bash):
% PYTHONPATH=~/PyChart-1.33/pychart python mumbo.py
* Documentation
A detailed documentation is found in doc/pychart.
* Examples
All the *.py files in the demos/ directory can be run directly. For
example,
setenv PYTHONPATH ..
python linetest.py >foo.eps
gs foo.eps
or
setenv PYTHONPATH ..
setenv PYCHART_OPTIONS="format=pdf"
python linetest.py >foo.pdf
acroread foo.pdf
* About the author
Yasushi Saito (ysaito@hpl.hp.com), a full-time researcher and
part-time hacker. This program is created mainly to serve my personal
needs to write pretty charts for research papers. As such, it is
updated only when I'm writing a paper, which happens about once every
half year or so.
Anyway, if you have comments, requests, or (even better)
fixes/enhancements, feel free to email me.
