Create a contour plot of the source


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


The contour_source command creates a contour plot of the source. To plot multiple contour components at the same time (e.g. fit, source, and residuals), use the contour command ("ahelp contour") .

The plot is displayed in a ChIPS plotting window. If there is no plotting window open, one is created. If a plotting window exists, the overcontour parameter value determines whether the new plot is overlaid on any existing plots in the window or if the window is cleared before the plot is drawn.

ChIPS commands may be used within Sherpa to modify plot characteristics and create hardcopies; refer to the ChIPS website for information.


Example 1

sherpa> contour_source()

Create a contour plot of the source for the default dataset, using the default settings.

Example 2

sherpa> contour_source("src", overcontour=True)

Make a contour plot of the source for dataset "src", overplotting if there is an existing ChIPS window.


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