Hi,
I agree, shell with inline plot is a different issue. I mainly coded
it as a proof a concept and because I find it useful for my own needs.
The figure call is quite different from the figure call of matplotlib,
only the name is common.
The idea was to be able to describe a configuration of arrays with a
minimum amount of code.
figure(Z) -> plot Z
figure([Z1,Z2]) -> plot Z1,Z2 side by side
figure([[Z1,Z2], [Z3,Z4]]) -> plot Z1,Z2 side by side and below, Z3,Z4
side by side
You can optionally indicate that an array spans several rows or columns:
figure([[Z1,'-'],
[Z3,Z4]]) -> plot Z1 on two columns and below, Z3,Z4 side by side
figure([[Z1,Z2],
['|', Z4]]) -> plot Z1 on two rows, then Z2 on first line and
Z4 on second line.
I looked at the thread you're talking about and it was the reason in
the first place that I investigated pyglet.
My approach is a bit different since I use a texture and a single quad
to render it, it makes things quite fast. The mapping from a float
array to a texture data is pretty efficient using numpy interface and
it allows me to continuously update texture data (just try modifying
the array from within the console).
