### 10-08-19 New quick update of values in charts

To make quick additional evaluation of results two new
check boxes have been introduced in the Window with output charts from the
model. The First checkbox *Sorted series of Y values* reorganize the chart
to be plotted as a serie from the smallest to the largest value of any time
serie. This allow the user to view the continous frequency distribution of any
output display. A click on the checkbox could be combined with one additional
click on the checkbox *Cumulated Y values* to display the corresponded
continuous cumulated frequency distribution of values. The Second new checkbox
*Versus Normal Distribution *replace the horizontal axis values of the
variable with the estimated values based on the normal distribution function
using the estimated std deviation and mean value of the variable. Both axis are
showing the cumulated values. The graph corresponds to the QQ-plot since we are
plotting quantiles from the cumulative distribution of the variable
against the theoretical normal distribution of the variable. A straight line
demonstrate that the variable equals a normal distribution
function.
