Yes, "Dark_Matter_Density field projections and slices" is what I meant. I will
try replacing "Density" with "Dark_Matter_Density".
Also, let me know if I am right...
p = pc.add_projection("Density", 0) ------- This is baryon density field.
p.modify["nparticles"](1.0) ------- But this is DM particles (since
there is no baryon particles dataset ?).

Subject: Re: [yt-users] DM particles or baryon density field ?
I guess the question is sort of ill-defined. Dark matter is
discretized as particles; the idea of projecting dark matter is not
the same as projecting a field quantity. The same goes for plotting
However, you can make dark matter plots. You cna use the
"add_particles" method on the PlotCollection, which accepts an axis
and a width -- what it does is plot all the particles within that
rectangular prism. This can be mocked up as a projection by setting
the width equal to the domain width along that axis.
You can also try using "Dark_Matter_Density", which might be easier to
visualize, as a projection or a slice.
If you run into any problems with the particle plot, let us know --
it's not as well-used as the other plots, so there might be subtle

The projection, slice, velocity and overplot particles routines: They read the DM

Looking at the density legend, it looks like this is baryon density field.
Is there a provision to plot projection and slice for DM ?
Also, I get this error when overplotting particles...
