ResidPlot

class sherpa.astro.plot.ResidPlot

Bases: sherpa.plot.ModelPlot

Create plots of the residuals (data - model) per point.

The value of (data-model) is plotted for each point.

plot_prefs

dict – The preferences for the plot.

x

array_like – The X value for each point.

y

array_like – The Y value for each point: data-model.

xerr

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

yerr

array_like – The error on the Y value, if set.

xlabel, ylabel, title

str – Plot labels.

Methods Summary

hline(y[, xmin, xmax, linecolor, linestyle, ...])	Draw a line at constant y, extending over the plot.
overplot(\*args, \*\*kwargs)	Add the data to an existing plot.
plot([overplot, clearwindow])
prepare(data, model, stat)
vline(x[, ymin, ymax, linecolor, linestyle, ...])	Draw a line at constant x, extending over the plot.
