""" new colormaps from old: stack, truncate builtin cmaps / files / numpy arrays

What's a colormap or cmap in matplotlib ?
Mainly a bar or array of 256 colors, rgb or rgba values 0 .. 1,
used in
    pl.imshow( a 2d numpy array, cmap=cmap, ... )
    pl.colorbar()
Cmaps can be indexed with () like
    cmap( .25 ),  cmap( [0, .25, .5] ),  cmap( np.linspace( ... ))

Automation for the People

Long ago, the first time I read "The Pragmatic Programmer", I read some advice that really stuck with me.

"Don't Use Manual Procedures".

This in the chapter on Ubiquitous Automation. To summarize, they want you to automate all the things.

The trouble was that I hadn't much of an idea how to actually go

salotz

  import matplotlib.pyplot as plt

  def move_axes(ax, fig, subplot_spec=111):
      """Move an Axes object from a figure to a new pyplot managed Figure in
      the specified subplot."""

      # get a reference to the old figure context so we can release it
      old_fig = ax.figure

      # remove the Axes from it's original Figure context

First start an ipython session first printing out the PID.

bash -c "echo $$; exec ipython"

I also tried changing the name of the process so you can name them but it didn’t seem to work, although there is probably something you can do to be able to do this:
