Menu: View results→Distribution
This option opens a window that shows information about the amount of entities with result on each span from a minimum and maximum of the result values.
Result must be an scalar or the modulus of a vectorial result or a component
The kind of graphs is similar to the 'Mesh quality' tool of preprocess. 
There are two visualization modes:
- Frequency: The graph shows the amount of items on each span.
- Accumulated: The graph shows the number of items which have of a equal or smaller result value.
In the Result distribution window, if you double click on a value, the items below this value are selected in red.
