AHELP for CIAO 4.3 Sherpa v1


Context: visualization


Open a contour plot in ChIPS


contour(contour1, [id1] ... [contourn, idn])


The contour() function opens contour plots in ChIPS to allow the user to visualize contours of a data set, model, fit, fit residuals, data-to-model ratio, or PSF, by dataset id.

  • contour1 ... contourn - the type of contour ('data', 'fit', etc.)
  • id1 ... idn - the id of the dataset to use for each contour; if not given, uses the default dataset id (id=1 by default, see "ahelp get_default_id")

Example 1

sherpa> contour( "data", 3)

A contour plot of data set 3 is visualized in ChIPS with this command.

Example 2

sherpa> contour( "data", "model", "fit", "resid" )

Here, a combination contour plot displays the data, model, fit, and fit residuals of the default data set in separate tiles of the ChIPS display, all to the same scale.

Example 3

sherpa> contour( "data", "bkg", "model", "bkg")

Contour plots of background data set "bkg" and its assigned model are sent to ChIPS for visualization.


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