vplot has been superseded by simpleSVG.
Why another plotting program?vplot translates user-friendly Python commands into user-nonhostile postscript. vplot is for those who are not afraid of knowing a bit about postscript.
Some users may find vplot lacking in capabilities and would need to add to the Python code in order to make the plots they need. You will need to know a bit about Python in order to use vplot, even if you do not intend to modify it. Some of my students were first exposed to Python in my course Information Technology Skills for Meteorology. vplot.py is currently a couple hundred lines of object-oriented Python.
vplot may be a good way to learn a little bit about object-oriented programming; it is the way I learned about it. vplot also helps me make plots that I could not make any other way, with what I find in the standard Linux distribution. See the examples at the bottom of this page.
I confess here that when I first heard of the term "vector graphics", I thought it was referring to plots with lots of little arrows. Nope, that is not what it means! Here are some definitions of "vector graphics".
