Frequency Plots

Frequency plots rank the data in each simulation, divide it into categories with the same range, and show the number of years of data that fall in each category. Frequency distributions are useful for analysing the skewness of the simulations and for identifying outliers.

To analyse simulations using box plots:

1. Open the [Charts] menu and select [Frequency…],
   …or click on the icon on the toolbar.
2. Select the data for analysis in the Frequency form. Choose the simulation(s) you wish to analyse in the upper selection window, and the data you wish to analyse in the lower window.
3. Choose the number of categories into which the data will be divided (1 to 10).
4. Choose whether to view a frequency or probability distribution.
