get_bkg_fit_plot

Synopsis

Return the data used by plot_bkg_fit.

get_bkg_fit_plot(id=None, bkg_id=None, recalc=True)

id - int or str, optional
bkg_id - int or str, optional
recalc - bool, optional

Examples

Example 1

Create the data needed to create the "fit plot" for the background of the default data set and display it:

>>> bplot = get_bkg_fit_plot()
>>> print(bplot)

Example 2

Return the plot data for data set 2, and then use it to create a plot:

>>> b2 = get_bkg_fit_plot(2)
>>> b2.plot()

Example 3

The fit plot consists of a combination of a data plot and a model plot, which are captured in the `dataplot` and `modelplot` attributes of the return value. These can be used to display the plots individually, such as:

>>> b2.dataplot.plot()
>>> b2.modelplot.plot()

or, to combine the two:

>>> b2.dataplot.plot()
>>> b2.modelplot.overplot()

Example 4

Return the plot data for the second background component to the "jet" data set:

>>> bplot = get_bkg_fit_plot('jet', bkg_id=2)

PARAMETERS

The parameters for this function are:

Return value

The return value from this function is:

model -- An object representing the data used to create the plot by `plot_bkg_fit` .
