A Graphical Analysis control can display arrows for each measured point. The length of the arrows indicate the point's deviation size.
This registry entry defines the number of best deviations for which to display arrows.
Because good deviations are small values, the arrows for the best deviations are quite small. You can increase the zoom level to see them better.
Entry Name: AnalysisViewArrowDensityBest
Entry Type: Number value that determines the number of best deviations.
