RMFPlot

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

Bases: HistogramPlot

Create plots of the ancillary response file (RMF).

A full RMF is a matrix that is hard to visualize. Here, we select a few specific energies and show the response function for those energies as histograms.

Attributes Summary

histo_prefs

The preferences for the plot.

labels

The labels for each line.

n_lines

rmf_plot_prefs

Plot preferences

title

Title of plot

x

Return (xlo + xhi) / 2

xhi

The upper edges of each bin.

xlabel

Label for X axis

xlo

The lower edges of each bin.

y

The response for a specific energy or channel.

ylabel

Label for Y axis

Methods Summary

overplot(*args, **kwargs)

plot([overplot, clearwindow])

Plot the data.

prepare(rmf[, data])

Fill the fields given the RMF.

Title of plot

x

Return (xlo + xhi) / 2

This is intended to make it easier to swap between plot- and histogram-style plots by providing access to an X value.

xhi = None

The upper edges of each bin.

Type:

array_like

xlabel = ''

Label for X axis

xlo = None

The lower edges of each bin.

Type:

array_like

y = None

The response for a specific energy or channel.

Type:

array_like

ylabel = ''

Label for Y axis

Methods Documentation

overplot(*args, **kwargs) [edit on github]
plot(overplot=False, clearwindow=True, **kwargs)[source] [edit on github]

Plot the data.

This will plot the data sent to the prepare method.

Parameters:
  • overplot (bool, optional) – If True then add the data to an existing plot, otherwise create a new plot.

  • clearwindow (bool, optional) – Should the existing plot area be cleared before creating this new plot (e.g. for multi-panel plotcs)?

  • **kwargs – These values are passed on to the plot backend, and must match the names of the keys of the object’s plot_prefs dictionary.

prepare(rmf, data=None)[source] [edit on github]

Fill the fields given the RMF.

Parameters:
  • RMF – The RMF to plot

  • data (DataPHA instance, optional) – The units attribute of this object is used to determine whether the X axis should be in Angstrom instead of KeV (the default).
