Python library and command line program to produce very small graphs without any wasted pixel for things like labels and axes. Has good xpm support
python -m tinygraph 1 2 3 4 5 > graph.xpm
python -m tinygraph 1 2 3 4 5 -o graph.bmp
# Big pixels on quite a large graph
python -m tinygraph 1 2 3 4 5 -o graph.bmp -p 3 -H 20
import tinygraph
image = tinygraph.tiny_graph(10, [1,2,3,4,5])
image.save('graph.xpm')
image.save('graph.bmp')
This library is well-suited for use with dzen2.
A utility dzengraph is provided to make this
a little easier
{python -m dzengraph graph1 1 2 3 4 5 5 5 ; sleep 10 } | dzen2
