plot_model

sherpa.astro.ui.plot_model(id=None, **kwargs)

Plot the model for a data set.

This function plots the model for a data set, which includes 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_model. 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.

Examples

Plot the convolved source model for the default data set:

>>> plot_model()

Overplot the model for data set 2 on data set 1:

>>> plot_model(1)
>>> plot_model(2, overplot=True)

Create the equivalent of plot_fit('jet'):

>>> plot_data('jet')
>>> plot_model('jet', overplot=True)
