[yt-users] Hop vs HaloProfiler

[Agarwal, Shankar]

Hi Stephen,

I am using the following statement...

    p.modify["hop_circles"](halos, max_number=None, annotate=True, min_size=400, max_size=100000, font_size=8, print_halo_size=True, print_halo_mass=True, width=None)


The plot is at http://drop.io/hop_circles

Why is it not printing the print_halo_mass ?
What are the options for width ?

shankar

hop_circles makes a plot of hop haloes on an existing projection. You need to create the projection first. So...

...
halos = HaloFinder(pf)
pc = PlotCollection(pf)
p = pc.add_projection("Density",0)
p.modify["hop_circles"](halos, max_number=etc...)
pc.set_width(1.0, '1')
pc.save('plotname')


My advice is, when you try to use a new function, you should figure out what it's doing and what the inputs are.
For example, even if your input was formatted correctly, you haven't defined 'self' or 'hop_output' before you
use them in the function call, and it would have failed anyway. Also, 'self' is a special variable in python
that is never used as an argument of a function call.

Good luck!
