AHELP for CIAO 4.3 Sherpa v1


Context: visualization


Open a contour plot of a data set model in ChIPS


contour_model( [ id, [replot=False,overcontour=False]] )


The contour_model function opens in ChIPS a contour plot of a data set model by data set ID. If no data set ID is specified, the model assigned to the default data set will be used. To plot contours of a data set, fit, fit residuals, data-to-model ratio, or psf, use the contour function.


  • id - Sherpa data set ID; if not given, uses the default dataset id (id=1 by default, see "ahelp get_default_id")
  • replot - Send cached data arrays to ChIPS; default=False
  • overcontour - Contour data without clearing previous plot; default=False

Example 1

sherpa> contour_model()

The contour_model function can be called with no arguments, in which case a contour plot of the model associated with the default data set loaded in the Sherpa session is visualized, with the default settings.

Example 2

sherpa> contour_model(3, overcontour=False)

Here, contour_model function clears the previous plot and sends to ChIPS a contour plot of the model assigned to data set 3.

Example 3

sherpa> contour_model(replot=True, overcontour=True)

This command sends to ChIPS a cached contour plot of the model assigned to data set 1, without clearing the previous plot.


See the bugs pages on the Sherpa website for an up-to-date listing of known bugs.
