Hi yt-users, I am trying to make some nice looking phaseplots, and want to set the mass range that I show in the figure. I use set_zlim and instead of only showing the cells that call into that mass range, it just changes the color coding. You can see the attached for what I am talking about. Is there a way to have phaseplot only show me the cells that have "cell_mass" larger that 1e36 (or whatever I happen to set)? Thanks! Stephanie -- Dr. Stephanie Tonnesen Alvin E.

Hi Stephanie,
One way to do this would be to create the PhasePlot using a cut_region data
object. If you're already using another data object to construct your phase
plot, the cut_region could be passed to the other data object via the
data_source keyword argument.

Hi Nathan and yt-users,
So I used the cut_region to only select cells with cell_mass > 1e36, and
got a surprising plot (I think). I am attaching both 2d profiles here for
comparison. I am not surprised that there are unfilled regions of the
figure--those may have been filled with cells that had less than 1e36 g,
although the positions are a bit strange. What I find really surprising is
that so much more of the figure that has the mass cut is yellow--shoudn't
there be equal or less mass than when I am not making a cut?
Thanks,
Stephanie

Ah sorry, I gave you bad advice in my initial e-mail.
The cut_region selects individual cells in your simulation that have masses
greater than the cutoff you chose. However that's not what the profile is
giving you. It's showing you regions in density-temperature parameter
space, with each box in this parameter space getting contributions from
several zones in your simulation. The reason your PhasePlot made from the
cut_region has "holes" you weren't expecting is that those regions are the
ones preferentially filled by low-mass zones in your simulation.
To get the plot you want you're going to need to mask out the 2D profile
PhasePlot uses to create the 2D histogram plot. The most straightforward
way to do this is to create the profile object manually using
create_profile, tweak it by zeroing out histogram bins that don't contain
enough mass, and then create a PhasePlot from the profile object using
PhasePlot.from_profile.
Here's a worked example showing how to do this:
https://gist.github.com/3a2afd006be4d1918f28d98ef2a1e077
Again, apologies for giving you bad advice on this issue initially, hope
this example helps.

Awesome! This looks like exactly what I want to do, thanks!
But here was my problem with the histograms--the gap made sense, just like
you said. What was really strange was that more of the histogram bins were
yellow in the "mcut" histogram--which has less mass to work with! So why
did cutting out the low mass gas make more of the histogram have higher
masses (the yellow)? This isn't dire, I am just wondering so I can
understand better how the code works.
Thanks,
Stephanie

Sure. It is pretty ugly, let me try to clean it up a little bit...
Okay, so for the first one, without the mass cut, diska and diskb were set
in the commented out lines and there was no disk2a or disk3b. The plot
commands were all the same. The rest of the code is just setting the
loop. Let me know if you want the whole code.
Here it is:
i =0
while i < len(loop):
ds =
yt.load("/data001/stonnes/BPr16vs30arccw/DD"+loop[i]+"/BPr16vs30arccw"+loop[i])
disk2 = ds.disk([0.5,0.5,0.5],[0,0,-1.0],(40,"kpc"),(5,"kpc"))
disk3 = ds.disk([0.5,0.5,0.5],[0,0,-1.0],(40,"kpc"),(10,"kpc"))
disk2a = disk2.cut_region(["obj['Metal_Density']/obj['density'] > 0.5"])
diska = disk2a.cut_region(["obj['cell_mass'] > 1e36"])
#diska = disk2.cut_region(["obj['Metal_Density']/obj['density'] > 0.5"])
disk3b = disk3.cut_region(["obj['Metal_Density']/obj['density'] > 0.5"])
diskb = disk3b.cut_region(["obj['cell_mass'] > 1e36"])
#diskb = disk3.cut_region(["obj['Metal_Density']/obj['density'] > 0.5"])
plot2 =
yt.PhasePlot(diska,"density","temperature",["cell_mass"],weight_field=None)
plot2.set_zlim('cell_mass',1e36,5e42)
plot2.save('BPr16vs30arccw'+loop[i]+'_5kpc_mcut')
plot2 =
yt.PhasePlot(diskb,"density","temperature",["cell_mass"],weight_field=None)
plot2.set_zlim('cell_mass',1e36,5e42)
plot2.save('BPr16vs30arccw'+loop[i]+'_10kpc_mcut')
i = i+1
