```
public TracePlotter(boolean hasVertical)
```
    Constructor.
    
    Parameters:
    
    hasVertical - true iff vertical fill is offered (otherwise only horizontal)
- 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 the Plotter.createStyle(uk.ac.starlink.ttools.plot2.config.ConfigMap) method.
    
    Returns:
    
    keys used when creating a style for this plotter.
  - createStyle
```
public TracePlotter.TraceStyle 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).
    
    Parameters:
    
    config - map of style configuration items
    
    Returns:
    
    plotter-specific plot style
  - createLayer
```
public PlotLayer createLayer(DataGeom geom,
                             DataSpec dataSpec,
                             TracePlotter.TraceStyle 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.
    
    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
