The Burst Statistics Cumulative Distribution Functions graph represents the normalized CDFs of all histograms computed when the Burst Analysis in the Burst Statistics Definitions tab is pressed.
Note that if:
the KDE checkbox
or the Logarithmic Binning checkbox
in that latter tab are checked, no CDF plot is computed.
An example of plots (corresponding to the statistics definitions shown in the illustration of the Burst Statistics Definitions manual page with no Logarithmic Binning) is shown below:
The Keep Burst Statistics CDF Plots checkbox ensures that newly computed plots are added to the list of existing plots (from previous computations). Note that the Analysis >> Clear All Burst Analysis Graphs menu item (Ctrl-Shift-D) will override this settings and clear the graph.
New plots take the name of the statistics they represent, as defined in the Burst Statistics Definitions tab (which is why using an alias may be preferable to using a complete formula). If a plot with the same name exists, the new plot gets a number in parenthesis added, as for all graphs in ALiX.
