function cumprobPlot(cost)
%CUMPROBPLOT    Create plot of datasets and fits
%   CUMPROBPLOT(COST)
%   Creates a plot, similar to the plot in the main distribution fitting
%   window, using the data that you provide as input.  You can
%   apply this function to the same data you used with dfittool
%   or with different data.  You may want to edit the function to
%   customize the code and this help message.
%
%   Number of datasets:  1
%   Number of fits:  0
