[yt-users] phase plot and time series

[Britton Smith]

Hi Mateusz,

Below is a reasonably simple way that someone might do something like
this.  This makes use of some newer functionality that currently only
exists in the development branch, so you would have to update to that to
use it.  This results in the following plot:

To do this, I first made some profiles over a time-series of datasets with
the following script:
http://paste.yt-project.org/show/6278/

The last line is the new functionality, which saves all of the compiled
profile data in a way that it can be reloaded as a yt dataset.  You can see
more information about that here:
http://yt-project.org/docs/dev/analyzing/saving_data.html

Now, yt is awfully close to being able to plot this itself, but not quite
there yet, so I plotted this using matplotlib.  The plotting script is here:
http://paste.yt-project.org/show/6279/

At the top of that script, you can see how I get access to the data that
was saved by the first script.  All that needs to be done is to call
yt.load with the file that was created and the data fields are all
accessible with full unit support through ds.data.  So, for example,
ds.data["density"].

I hope this is helpful.
