[IPython-dev] Notebook: Horizontal layout for multiple figures in output cell

I have a very similar workflow and agree that plotting and arranging
figures is not as easy or flexibe as it could be. However, my approach
is slightly different: All my plots are subplots. I usually define
each subplot in a separate function that takes Axes as an argument
(this could be extended to directly create a new figure if no axes
argument is passed). I then create a figure with a number of columns
and rows and attach the previously defined subplots in a convenient
order. I usually iterate the defined subplots and the arrangement of
the subplots until I am happy with the figure.

It should be easier to rearrange (sub)plots, but I am not sure if the
IPython notebook / HTML is the right place to do it. If matplotlib
would make this more convenient this might be all we need.

I just played around with moving / copying axes (subplots) between
figures in matplotlib and while I think it's supposed to work and
works to some extend, it does not work properly (e.g. size, position,
axes of the subplots are wrong when reattached to a different figure).
