plot_source

sherpa.ui.plot_source(id=None, **kwargs)

Plot the source expression for a data set.

This function plots the source model for a data set. This does not include any instrument response (e.g. a convolution created by set_psf).

Parameters:
  • id (int or str, optional) – The data set that provides the data. If not given then the default identifier is used, as returned by get_default_id.
  • replot (bool, optional) – Set to True to use the values calculated by the last call to plot_source. The default is False.
  • overplot (bool, optional) – If True then add the data to an exsiting plot, otherwise create a new plot. The default is False.
