Directional plot

Directional plot, or Migration plot, is one of the charting options available in the Charts Panel. It aligns the starting position of all selected track objects to the origin and plots their X and Y positions relative to the origin over time. This chart is very useful for finding track migration patterns.

To display the Directional plot, open the Charts Panel and select the Directional plot option  from the Charts selection dropdown menu.
