plot_data

sherpa.astro.ui.plot_data(id=None, **kwargs)

Plot the data values.

Parameters:

• id (int or str, optional) – The data set that provides the data. If not given then the default identifier is used, as returned by get_default_id.
• replot (bool, optional) – Set to True to use the values calculated by the last call to plot_data. The default is False.
• overplot (bool, optional) – If True then add the data to an exsiting plot, otherwise create a new plot. The default is False.

sherpa.astro.ui.set_analysis()

Set the units used when fitting and displaying spectral data.

set_xlinear()

New plots will display a linear X axis.

set_xlog()

New plots will display a logarithmically-scaled X axis.

set_ylinear()

New plots will display a linear Y axis.

set_ylog()

Examples

Plot the data from the default data set:

>>> plot_data()

Plot the data from data set 1:

>>> plot_data(1)

Plot the data from data set labelled “jet” and then overplot the “core” data set. The set_xlog command is used to select a logarithmic scale for the X axis.

>>> set_xlog("data")
>>> plot_data("jet")
>>> plot_data("core", overplot=True)
