plot_order

Context: plotting

Synopsis

Plot the model for a data set convolved by the given response.

Syntax

plot_order(id=None, orders=None, replot=False, overplot=False,
clearwindow=True, **kwargs)

id - int or str, optional
orders - optional
replot - bool, optional
overplot - bool, optional
clearwindow - bool, optional

Description

Some data sets - such as grating PHA data - can have multiple responses. The `plot_order` function acts like `plot_model` , in that it displays the model after passing through a response, but allows the user to select which response to use.


Examples

Example 1

Display the source model convolved by the first response for the default data set:

>>> plot_order(orders=1)

Example 2

Plot the source convolved through the first and second responses for the second data set (separate curves for each response):

>>> plot_order(2, orders=[1, 2])

Example 3

Add the orders plot to a model plot:

>>> plot_model()
>>> plot_order(orders=[2, 3], overplot=True)

PARAMETERS

The parameters for this function are:

Parameter Definition
id The data set that provides the data. If not given then the default identifier is used, as returned by `get_default_id` .
orders Which response to use. The argument can be a scalar or array, in which case multiple curves will be displayed. The default is to use all orders.
replot Set to True to use the values calculated by the last call to `plot_model` . The default is False .
overplot If True then add the data to an existing plot, otherwise create a new plot. The default is False .
clearwindow Should the existing plot area be cleared before creating this new plot (e.g. for multi-panel plots)?
