I am trying to create some brand new types of plots for a unique data set
that I have. My question basically boils down to getting some advice on
what is the proper way to set up a function that will act like one of the
matplotlib pyplot functions (e.g., have all the same behavior regarding
interactive stuff, resizing, etc.).
Most of the pyplot functions are wrapper around the method in the Axes class.
For example, pyplot.plot is basically
ax = gca()
And the basic role of the plotting method in the Axes class is to
matplotlib artists and add them to the axes. If your plot can be
created with matplotlib's currently existing artists, you can simply
reuse them. Otherwise, you need to create your own artist, but this
requires some understandings of internals.
def ax_my_plot(ax, *kl, **ka):
# create artists and add them to ax
def my_plot(*kl, **ka):
ax = gca()
ax_my_plot(ax, *kl, **ka)
"my_plot" will behave similar to other pyplot command.
I have been looking through some of the code for the major functions like
plot, but have been having trouble parsing it. I think that some of this is
obfuscated in the complexity of the functions.
At some level, I would also like to be able to draw on the canvas in a very
explicit way, like in Processing (http://processing.org/); what is the best
way to approach this?
You can draw something in the canvas coordinate. But what you can do
is limited by the matplotlib's backend api, which is more like a
vector drawing tool. So things like a pixel manipulation is not

Another thing that could be really nice is to have some boilerplate
framework that someone could start with to quickly write functions that
integrate well into the rest of matplotlib.
(And sorry if I am sounding critical of the package. I actually love it,
and have been quite the MPL evangelist in my little section of Boston.)
Any suggestions are welcome.
