Changing the Persistence Time
Changing the Persistence Time
In the Display menu you can change the persistence time by choosing a
number of layers and the number of samples per layer. In this way you can
determine the total number of samples on the screen. Since the
persistence time depends on the speed of the host computer, this allows
for a selection better adapted for each user.
To change the persistence time:
1. From the main window, select the Display menu.
2. Select Persistence, then select the number of layers to use.
