ChisqrPlot

class sherpa.astro.plot.ChisqrPlot[source] [edit on github]

Bases: sherpa.plot.ModelPlot

Create plots of the chi-square value per point.

The value of ((data-model)/error)^2 is plotted for each point.

plot_prefs

The preferences for the plot.

Type:dict
x

The X value for each point.

Type:array_like
y

The Y value for each point: ((data-model)/error)^2

Type:array_like
xerr

The half-width of each X “bin”, if set.

Type:array_like
yerr

The error on the Y value. Will be None here.

Type:array_like
xlabel, ylabel, title

Plot labels.

Type:str
