Changing Layout Theta

The layout theta determines the accuracy of the Barnes–Hut approximation computation; larger values increase the speed of the simulation but lower its accuracy. When theta is 0, the algorithm becomes a direct-sum algorithm.

To change the layout theta setting, navigate to the Marks menu, and change value for Layout theta option. The default setting is 0.8.
