AHELP for CIAO 4.9 Sherpa v1

contour_source

Context: visualization

Synopsis

Create a contour plot of the source

Syntax

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

Description

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") .

  • id - the id of the dataset to use; if not given, uses the default dataset id (id=1 by default, see "ahelp get_default_id")
  • replot - should the cached arrays be used in the plot? False (default)=do the calculation, True=redisplay the existing values
  • overcontour - overplot the contour? default=False (clear the window before plotting)

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.

Bugs

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