createLayer
public PlotLayer createLayer(DataGeom geom, DataSpec dataSpec, S style)
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 ifgetCoordGroup()
.getPositionCount
returns 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 space; if non-null, the data geom'sDataGeom.hasPosition()
method will return truedataSpec
- 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
protected abstract LayerOpt getLayerOpt(S style)
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, java.awt.Graphics g, PaperType paperType)
Called during Decal painting to perform the actual plot.- Parameters:
