AHELP for CIAO 4.9 Sherpa v1


Context: plotting


Plot the convolved source model by order


plot_order( [id], orders, [replot=False, overplot=False] )


The plot_order command plots the convolved source model by multiple response order.

  • 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")
  • orders - list of orders to plot
  • replot - should the cached arrays be used in the plot? False (default)=do the calculation, True=redisplay the existing values
  • overplot - should the new plot be overlaid in the plotting window? False (default)=clear the window, True=overplot on any existing plots

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 overplot 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.

Plotting Multiple Objects

To plot multiple Sherpa objects - e.g. data, model, fit, residuals - in a single window, use the plot command.

Example 1

sherpa> plot_order("src", orders="[1,-1]")

Plot the convolved source model for orders 1 and -1 of the dataset "src".

Example 2

sherpa> plot_order(2, 2, overplot=True )

Plot the convolved source model for the second order of data id=2, overlaying it on any existing plot.


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