A simple wrapper for Gnuplot

Project description

by Wicher Minnaard <> <>

This is public domain software.

Difference with gnuplot-py: This module does not need numpy. Also, this module doesn’t offer tight integration with gnuplot.

The main problem this module solves is that gnuplot needs a) data, b) instructions, and generates c) graph output. a) comes from files, b) can be fed in stdin, and c) can be written to stdout and used in your Python code.

For instance, you may want to feed data from Python into gnuplot according to some dynamically generated instructions, catch some SVG back in a Python string, and push that out over HTTP without messing with temporary files.

But if you want to feed _data_ from Python into gnuplot, then you must use temporary files because stdin is reserved for instructions.

This module employs filesystem FIFOs and doesn’t write data to disk.

This version works with Python 2.7 and 3.1+.
