ArepoCubicGrid.plot_slice(x=None, y=None, z=None, length_unit=None, ndensity_unit=Unit('1 / cm3'), log=False, mask_below=None, cmap='magma', save=None, **kwargs)[source]#

Plot a slice of 3D number density grid.

Parameters:

  • x (int, optional) – Integer corresponding to \(x\)-slice of the grid. One of x, y or z is required.

  • y (int, optional) – Integer corresponding to \(y\)-slice of the grid. One of x, y or z is required.

  • z (int, optional) – Integer corresponding to \(z\)-slice of the grid. One of x, y or z is required.

  • length_unit (Unit, optional) – The unit of length to use. If None (default), takes the value u.pix if scale='pixel', else u.cm if scale='physical'.

  • ndensity_unit (Unit, optional) – The unit of number density to use. Default value is u.cm**-3.

  • log (bool, optional) – If True, the number density is plotted on a log-scale. If False (default), it is plotted on a linear scale.

  • mask_below (float or Quantity, optional) – The number density below which all grid points are omitted from the plot. This ensures only certain dense regions are plotted. If float, then assumed to be in ndensity_unit units.

  • cmap (str or Colormap, optional) – Colormap of the plot. Default is 'magma'.

  • save (str, optional) – File path to save the plot. If None (default), plot is not saved.

  • **kwargs (dict, optional) – Additional matplotlib-based keyword arguments to control finer details of the plot.

Returns:

fig (Figure) – Main Figure instance.
