You can use the check box for Display line coverage symbols to show or hide symbols for line coverage (hit, partially hit, and missed) in the left margin of the annotated source code display. If you hide the symbols, hit, partially hit, and missed lines are distinguished only by color.
The Source Lookup Path list specifies the search paths for locating source code that is not in a project in your workspace. Click Add or Remove to modify the list.
You can customize the colors in the pie charts for hit, partially hit, and missed lines. You can also customize the fonts used in the Coverage Summary chart.
Click Restore Defaults to reset the display.
You can customize the style (font text and size, foreground and background color, and attributes) for individual categories of text in the source display. For example, you can choose to have partially covered lines displayed with an underline and a magenta background.
