void |
setPlotArea(boolean flag)
Sets a flag that controls whether or not areas are drawn for each data item. |
void |
setPlotShapes(boolean flag)
Sets the flag that controls whether or not shapes are displayed for each data item. |
void |
setRangeBase(double val)
Sets the value on the range axis which defines the default border of the area. |
void |
setShapesFilled(boolean filled)
