Plot the surface density of a set of potentials.

  • Pot (Potential or list of Potential instances) – Potential(s) for which to plot the surface density.

  • xmin (float or Quantity) – Minimum x value. Default is -1.5.

  • xmax (float or Quantity) – Maximum x value. Default is 1.5.

  • nxs (int) – Number of grid points in x.

  • ymin (float or Quantity) – Minimum y value. Default is -1.5.

  • ymax (float or Quantity) – Maximum y value. Default is 1.5.

  • nys (int) – Number of grid points in y.

  • z (float or Quantity, optional) – Height between which to integrate the density (from -z to z). Default is numpy.inf.

  • t (float, optional) – Time to use to evaluate potential. Default is 0.0.

  • ncontours (int, optional) – Number of contours. Default is 21.

  • justcontours (bool, optional) – If True, just plot contours. Default is False.

  • aspect (float, optional) – Aspect ratio of the plot. Default is None.

  • savefilename (str, optional) – Save to or restore from this savefile (pickle). Default is None.

  • log (bool, optional) – If True, plot the log density. Default is False.

  • **kwargs (dict, optional) – Additional keyword arguments to pass to plot.dens2d.
