question: private void calculateMaxValue ( int seriesCount , int catCount ) { double v ; Number nV ; for ( int seriesIndex = 0 ; seriesIndex < seriesCount ; seriesIndex ++ ) { for ( int catIndex = 0 ; catIndex < catCount ; catIndex ++ ) { nV = getPlotValue ( seriesIndex , catIndex ) ; if ( nV != null ) { v = nV . doubleValue ( ) ; if ( v > this . maxValue ) { this . maxValue = v ; } } } } }
target:  loop through each of the series to get the maximum value on each category axis
