A large number of markers on a JMP graph can appear crowded. You might need to alter the transparency to gain a better view. Altering the transparency might also affect the marker drawing mode, which is the mode JMP uses when it refreshes a report window. As markers are drawn on a plot, JMP uses one of two speeds: normal or fast.
To change the marker drawing speed
1. Right-click anywhere in a graph. In a histogram, right-click the box plot area on the right.
2. Select Marker Drawing Mode, and then select either Normal or Fast.
Normal
If JMP is in normal drawing mode and the number of markers on a graph are more than the specified threshold number, JMP automatically switches to fast mode. See Preferences for Data Tables for more information about setting the marker threshold.
Fast
Graphs that display a large number of markers appear faster if you set the marker drawing speed to Fast. Note that when the drawing speed is set to Fast, the smallest marker size (Dot) is applied, and marker transparency settings revert to the default opaqueness.
Outlined
See Add Outlines Around Markers.
To fill hollow markers
In the JMP preferences, select Graphs and then select Fill Hollow Markers. Hollow markers on all graphs are filled with an opaque background.
