Detailed Description

Bar plot abstract class.

It is expected to take data in the form of PlotPointData. The line methods in Plot are used for the bar outlines.

virtual void casa::BarPlot::setAreaFilled ( bool  fill = true )

pure virtual

Sets whether the bars have an area fill.

If fill is true, the implementation can decide whether to choose the area fill, or just use the last set PlotAreaFill.
