Plotter
The style
parameter is the result of a call to
Plotter.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
getCoordGroup()
.
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.
geom
- indicates base position coordinates and their
mapping to points in the data space;
if non-null, the data geom's
DataGeom.hasPosition()
method will return truedataSpec
- specifies the data required for the plotstyle
- data style as obtained from createStyle
