```
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 the Plotter.createStyle(uk.ac.starlink.ttools.plot2.config.ConfigMap) method.
    
    Specified by:
    
    getStyleKeys in interface Plotter<Stats1Plotter.StatsStyle>
    
    Returns:
    
    keys used when creating a style for this plotter.
  - createStyle
```
public Stats1Plotter.StatsStyle 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 by Plotter.getStyleKeys(). The return value can be used as input to Plotter.createLayer(uk.ac.starlink.ttools.plot2.DataGeom, uk.ac.starlink.ttools.plot2.data.DataSpec, S).
    
    Specified by:
    
    createStyle in interface Plotter<Stats1Plotter.StatsStyle>
    
    Parameters:
    
    config - map of style configuration items
    
    Returns:
    
    plotter-specific plot style
  - createLayer
```
public PlotLayer createLayer(DataGeom geom,
                             DataSpec dataSpec,
                             Stats1Plotter.StatsStyle 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 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.
    
    Specified by:
    
    createLayer in interface Plotter<Stats1Plotter.StatsStyle>
    
    Parameters:
    
    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 true
    
    dataSpec - specifies the data required for the plot
    
    style - data style as obtained from createStyle
    
    Returns:
    
    new plot layer, or null if no drawing will take place
