createLayer
Description copied from interface:Plotter
Creates a PlotLayer based on the given geometry, data and style.The
style
parameter is the result of a call toPlotter.createStyle(uk.ac.starlink.ttools.plot2.config.ConfigMap)
.The
dataSpec
parameter must contain the coordinates defined by this plotter's CoordGroup.The
pointDataGeom
parameter is only used if theCoordGroup.getBasicPositionCount()
orCoordGroup.getExtraPositionCount()
method from this plotter's CoordGroup return a non-zero value, otherwise the plot does not have point positions.It is legal to supply null for any of the parameters; if insufficient data is supplied to generate a plot, then the method should return null.
Creating a layer should be cheap; layers may be created and not used.
- Parameters:
geom
- indicates base position coordinates and their mapping to points in the data spacedataSpec
- specifies the data required for the plotstyle
- data style as obtained fromcreateStyle
- Returns:
- new plot layer, or null if no drawing will take place
-
getLayerOpt
Indicates the layer optimisation options that apply to a given style.- Parameters:
style
- plot style- Returns:
- layer options

paintData2D
protected abstract void paintData2D(Surface surface, DataStore dataStore, DataGeom geom, DataSpec dataSpec, S style, Graphics g, PaperType paperType) Called during Decal painting to perform the actual plot.- Parameters:
