Accessing the data used to create a plot [New]


Virtually all of the plot_xxx functions have an associated get_xxx_plot function which returns a Pyton object containing the data that is used to create the plot. This can be used if you want to create your own version of the plot, or if you want to use the data for further analysis (accessing PHA data in units of keV or Angstrom can be surprisingly complex to do, so using the plot infrastructure is often the quickest way to get at the information). The data for multi-plot routines like plot_fit_resid is accessed with the individual component calls - so in this case get_fit_plot and get_resid_plot.

The basic plots are supported:
Plot Data access Comments
plot_chisqr get_chisqr_plot
plot_data get_data_plot
plot_delchi get_delchi_plot
plot_fit get_fit_plot The return structure contains dataplot and modelplot attributes which contains the plotted data.
plot_kernel get_kernel_plot
plot_psf get_psf_plot
plot_ratio get_ratio_plot
plot_resid get_resid_plot
The background variants are also supported:
Plot Data access Comments
plot_bkg_chisqr get_bkg_chisqr_plot
plot_bkg_delchi get_bkg_delchi_plot
plot_bkg_fit get_bkg_fit_plot The return structure contains dataplot and modelplot attributes which contains the plotted data.
plot_bkg get_bkg_plot
plot_bkg_ratio get_bkg_ratio_plot
plot_bkg_resid get_bkg_resid_plot
plot_bkg_source get_bkg_source_plot
Plotting the model.
Plot Data access
plot_model get_model_plot
plot_source get_source_plot
plot_model_component get_model_component_plot
plot_source_component get_source_component_plot
plot_order get_order_plot

There are also a number of specialized commands:

Plot Data access
plot_arf get_arf_plot
plot_rmf [New] get_rmf_plot [New]
plot_pvalue get_pvalue_plot
plot_pdf get_pdf_plot
plot_cdf get_cdf_plot
plot_scatter get_scatter_plot
plot_trace get_trace_plot
