       Name: stepAxis                                                [Show more]
       Type: Variable
   Category: Dashboard
    Summary: Code modifications for the DrawDashboardLine line-drawing routine
    Context: See this variable in context in the source code
 References: This variable is used as follows:
             * DrawDashboardLine uses stepAxis


 When drawing a line, we step along the longer axis of the line's vector by one
 pixel for loop around the line-drawing routine. See the DrawDashboardLine
 routine for details.
