Update PPM Chart Selection Properties
Custom properties let you control the color and how opaque the highlight is that is used to show a selection when users click in a PPM Chart:
1. Click 
Configure in the title bar of the PPM Chart app. 2. Select Properties and click the Properties tab.
3. If desired, change how opaque the select highlight color is in the Select Opacity property. Higher values make the color more opaque.
4. If desired, enter a hexadecimal code for the highlight color to use to indicate selection. The default color, 0000ee, is a very pale blue.
5. Click Apply.
