Frequency Plots
Example of a frequency plot. click to enlarge
Frequency plots, opened from the caliper strip (caliper > Caliper Analysis > Frequency Plots) show the frequency of breakouts in two ways, as a histogram and as a rose diagram.
You can adjust how the data is visualized in the plots using the context menu of the plots, or by using the options in the Display panel, opened from the toolbar (
).
