plot_arf

Context: plotting

Synopsis

Plot an ARF

Syntax

plot_arf( [id], [resp_id=None, overplot=False] )

Description

The plot_arf command plots an ARF (effective area) associated with the dataset.

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.


Examples

Example 1

sherpa> plot_arf()

Plot the first ARF associated with the default dataset.

Example 2

sherpa> plot_arf("src", "arf2", overplot=True)

Plot the ARF "arf2" associated with dataset "src", overlaying it on any existing plots.


Bugs

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