Detailed Description

Scatter plot abstract class.

In addition to the abstract methods in Plot, a scatter plot subclass should also have symbol customization for the points. A scatter plot is expected to consist of PlotPointData.

virtual void casa::ScatterPlot::setSymbolsShown

(

bool

symbolsShown = true

)

[pure virtual]

Sets whether symbols are shown or not.

If symbolsShown is true, the implementation can decide whether to choose the symbol shown, or just use the last set PlotSymbol.

Referenced by setSymbol().

virtual PlotSymbolPtr casa::ScatterPlot::symbol

(

)

const [pure virtual]

Returns a copy of the symbol for this plot.

Note: if symbols are not shown, then this behavior is undefined. The last shown symbol can be returned, or a symbol with style NOSYMBOL, or a null pointer, or...\.

Referenced by setSymbol(), setSymbolAreaFill(), setSymbolLine(), and setSymbolSize().

virtual bool casa::ScatterPlot::symbolsShown

(

)

const [pure virtual]

Returns true if symbols are shown, false otherwise.
