◆ fillAlpha()

qreal RadarDiagram::fillAlpha ( ) const

Fill the areas of the radar chart with there respective color defined via KDChart::DatasetBrushRole. The value defines the alpha of the color to use. If set to 0.0 (the default) then the radar areas will not be filled with any color. If set to 1.0 then the areas will be solid filled and are not transparent.
