AHELP for CIAO 4.9 Sherpa v1


Context: visualization


Open a contour plot of a data set in ChIPS


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


The contour_data() function opens in ChIPS a contour plot of a data set by data set ID. If no data set ID is specified, the default data set will be used. To plot contours of a model, 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_data()

The contour_data function can be called with no arguments, in which case a contour plot of the data is made for the first data set loaded in the Sherpa session, with the default settings.

Example 2

sherpa> contour_data(3, overcontour=False)

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

Example 3

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

This command sends to ChIPS a cached contour plot of 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.
