ARFPlot
- class sherpa.astro.plot.ARFPlot[source] [edit on github]
Bases:
HistogramPlot
Create plots of the ancillary response file (ARF).
- xlo, xhi
The lower and upper edges of each bin.
- Type:
array_like
- y
The effective area (ARF) value for the bin.
- Type:
array_like
- xlabel, ylabel, title
Plot labels.
- Type:
Attributes Summary
The preferences for the plot.
Return (xlo + xhi) / 2
Methods Summary
hline
(y[, xmin, xmax, linecolor, linestyle, ...])Draw a line at constant y, extending over the plot.
overplot
(*args, **kwargs)plot
([overplot, clearwindow])Plot the data.
prepare
(arf[, data])Fill the fields given the ARF.
vline
(x[, ymin, ymax, linecolor, linestyle, ...])Draw a line at constant x, extending over the plot.
Attributes Documentation
- histo_prefs = {'alpha': None, 'capsize': None, 'color': None, 'ecolor': None, 'label': None, 'linestyle': 'solid', 'linewidth': None, 'marker': 'None', 'markerfacecolor': None, 'markersize': None, 'xerrorbars': False, 'xlog': False, 'yerrorbars': False, 'ylog': False}
The preferences for the 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.
Methods Documentation
- static hline(y, xmin=0, xmax=1, linecolor=None, linestyle=None, linewidth=None, overplot=False, clearwindow=True) [edit on github]
Draw a line at constant y, extending over the plot.
- overplot(*args, **kwargs) [edit on github]
- plot(overplot=False, clearwindow=True, **kwargs) [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 plots)?
**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(arf, data=None)[source] [edit on github]
Fill the fields given the ARF.
- Parameters:
arf – The ARF 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). If the units setting is “channel” then the X axis is shown using keV.
- static vline(x, ymin=0, ymax=1, linecolor=None, linestyle=None, linewidth=None, overplot=False, clearwindow=True) [edit on github]
Draw a line at constant x, extending over the plot.
