Histogram Plot

To plot a histogram of results after a Probabilistic analysis:

1. Select Plot Histogram on the toolbar or the Statistics menu to open the Histogram Plot dialog.
   
2. Select the data you want to plot in the Data to Plot (e.g., Factor of Safety or one of the parameters you've defined as a random variable).
3. Enter a Number of Bins. The default is 30, but any value between 2 and 100 can be entered.
4. To highlight data in the plot with a Factor of Safety lower than a certain number, select the Highlight Data check box and enter a value ( the default = 1).
5. Click Plot.
   The histogram is generated in the Histogram View, and the mean, standard deviation, and minimum and maximum values for the data plotted are displayed at the bottom, as shown in the figure below.

Best Fit Distribution

If the Data to Plot is Factor of Safety, a Best Fit Distribution is determined and can be displayed on the histogram along with the distribution parameters.

Input Distribution

If the Data to Plot is a random variable, the Input Distribution can be plotted.
