get_delchi_plot

Synopsis

Return the data used by plot_delchi.

get_delchi_plot(id=None, recalc=True)

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

Examples

Example 1

Return the residual data, measured in units of the error, for the default data set:

>>> rplot = get_delchi_plot()
>>> np.min(rplot.y)
-2.85648373819671875
>>> np.max(rplot.y)
2.89477053577520982

Example 2

Display the contents of the residuals plot for data set 2:

>>> print(get_delchi_plot(2))

Example 3

Overplot the residuals plot from the 'core' data set on the 'jet' data set:

>>> r1 = get_delchi_plot('jet')
>>> r2 = get_delchi_plot('core')
>>> r1.plot()
>>> r2.overplot()
