Applies to: @RISK 5.x and Up

How Does @RISK Determine the Number of Histogram Bars and Can I Change It?

Answer:

By default, @RISK determines the number of bins from the number of iterations or data points n, as follows:

n	Bins
Less than 25	5
25 to 100	Nearest integer to n/5
More than 100	Largest integer below 10 x log (n)

 

If you want to change this:

1. Right-click the graph and select Graph Options.
   1. On the Distribution tab, the lower section lets you specify a number of bins (bars), as well as a minimum (left edge of the first bar) and maximum (right edge of the last bar).
   2. "Automatic" uses the calculation shown above, but you can specify a number from 2 to 200.
