[yt-users] Multiplot Phaseplot

[Matthew Turk]

Hi Christine and Charles,

This is something I've been looking at recently.  The PlotCollection
as a whole has not aged ... particularly well.  It was designed for a
mode of operation which is 4 years obsolete at this point.  To that
end, I've been working on isolated phase and profile plots, and Jeff
Oishi has been working on the Plot Window.  These are designed to be
independent of Plot Collections, and are supposed to be more agile;
more control is left to the user for setting up contexts, and fewer
knobs and twiddles will be provided, on the basis that ... it's hard
to get that right reliably.

The phase plots and profile plots currently work, and I have been
using them for a paper I am currently writing.  I've also figured out
how to correlated colorbars across image plots of projections&slices,
if you end up needing any code for that, inside the multiplot context.

The sample script I came up with for generating phase plots is here:

http://paste.enzotools.org/show/1689/

The idea here is that it creates a figure, and then for each plot it
creates a new subplot, into which it plots our plot.  You can then use
the standard Matplotlib colors and limits and so on and so forth.

Hope that helps,

Matt
