% This function obtains a plot of the load cycle for a given interval.
% The demand interval and the load must be defined by the variable data
% in a three-column matrix.  The first two columns are the demand
% interval and the third column is the load value. The demand interval
% may be minutes, hours, or month in ascending order.  Hourly intervals
% must be expressed in military time.
