question: public void computeXAxis ( ) { xStops . numStops = visibleXRange ; if ( xStops . stops . length < visibleXRange ) { xStops . stops = new float [ visibleXRange ] ; } int value = ( int ) Math . ceil ( viewportRect . left ) ; for ( int i = 0 ; i < visibleXRange ; i ++ , value += xInterval ) { xStops . stops [ i ] = value ; } }
target:  Compute stops for X Axis
