[yt-users] plot collection labels etc

[Geoffrey So]

Hi all,

I just want to address the PlotCollection question on colorbar for phase
diagrams, since I've ran into the same problem a while back.  Chris' method
of "myprojection.set_label("H_NumberDensity")" didn't work for me at least
in phase plots.

"I still need to use PlotCollection for phase plots (Is there equivalent
things for phase plots?),
and the problem persists. For example, ‘H_NumberDensity’ shows ’N’ as a
subscript."

http://paste.yt-project.org/show/4043/

- In the script under method 2, what I've done is use yt for the gathering
of data (very quick with lazy_reader=True with multiple processors even on
big datasets) and use matplotlib to do custom labels.  This is more
flexible in terms of the customizations you want to do, but it's also a lot
of trial and error and digging through matplotlib's burdensome
documentation.

Hope that solves your trouble Semyeong

Questions I have:

- will the new function that replaces PlotCollection's phase plot
functionality going to use BinnedProfile2,3D in yt-3.0?  Or will I have to
rewrite scripts that uses it currently?

- Since the phase plot bins the data in equal spaced bins in log space when
it is specified, shouldn't the pixels when plotted in log scale be also
different size?  Or better yet, shouldn't the x, y axis be labeled as Log
x: 0 1, 2, 3 instead of x: 10^0, 10^1, 10^2, 10^3?

From
G.S.
