Method Detail
-
getPlotterDescription
public java.lang.String getPlotterDescription()
Description copied from interface:Plotter
Returns an XML description of this plotter.Note: really this should appear at the LayerType level.
- Returns:
- one or more <p> elements
-
getStyleKeys
public ConfigKey[] getStyleKeys()
Description copied from interface:Plotter
Returns the configuration keys used to configure style for this plotter. The keys in the return value are used in the map supplied to thePlotter.createStyle(uk.ac.starlink.ttools.plot2.config.ConfigMap)
method.- Returns:
- keys used when creating a style for this plotter.
-
createStyle
public SphereGridPlotter.GridStyle createStyle(ConfigMap config)
Description copied from interface:Plotter
Creates a style that can be used when creating a plot layer. The keys that are significant in the supplied config map are those returned byPlotter.getStyleKeys()
. The return value can be used as input toPlotter.createLayer(uk.ac.starlink.ttools.plot2.DataGeom, uk.ac.starlink.ttools.plot2.data.DataSpec, S)
.- Parameters:
config
- map of style configuration items- Returns:
- plotter-specific plot style
-
createLayer
public PlotLayer createLayer(DataGeom geom, DataSpec dataSpec, SphereGridPlotter.GridStyle 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
