[yt-users] Over plot particles

[REMUDIN RESHID MEKURIA]

Dear all,

Thank you for your help in advance.
I am currently running cosmological simulations using Nyx code.
And while trying to over plotting particles on the density slice, I encountered the following error which I couldn't resolve. I will greatly appreciate your help.

Traceback (most recent call last):
  File "./OverPlotingParticles.py", line 14, in <module>
    pc.set_width(1.0, '1') # change width of our plot to the full domain
  File "/home/uni06/cosmo/rmekuri/yt-x86_64/src/yt-hg/yt/visualization/plot_collection.py", line 267, in set_width
    plot.set_width(width, unit)
  File "/home/uni06/cosmo/rmekuri/yt-x86_64/src/yt-hg/yt/visualization/plot_types.py", line 441, in set_width
    self._refresh_display_width()
  File "/home/uni06/cosmo/rmekuri/yt-x86_64/src/yt-hg/yt/visualization/plot_types.py", line 459, in _refresh_display_width
    self._redraw_image()
  File "/home/uni06/cosmo/rmekuri/yt-x86_64/src/yt-hg/yt/visualization/plot_types.py", line 406, in _redraw_image
    self._run_callbacks()
  File "/home/uni06/cosmo/rmekuri/yt-x86_64/src/yt-hg/yt/visualization/plot_types.py", line 259, in _run_callbacks
    cb(self)
  File "/home/uni06/cosmo/rmekuri/yt-x86_64/src/yt-hg/yt/visualization/plot_modifications.py", line 985, in __call__
    &   ( reg[field_y] >= y0 ) & ( reg[field_y] <= y1 ) )
  File "/home/uni06/cosmo/rmekuri/yt-x86_64/src/yt-hg/yt/data_objects/data_containers.py", line 319, in __getitem__
    self.get_data(key)
  File "/home/uni06/cosmo/rmekuri/yt-x86_64/src/yt-hg/yt/data_objects/data_containers.py", line 2410, in get_data
    if self._generate_field(field):
  File "/home/uni06/cosmo/rmekuri/yt-x86_64/src/yt-hg/yt/data_objects/data_containers.py", line 352, in _generate_field
    raise KeyError(field)
KeyError: 'particle_position_y'

With best regards,

Cheers,
