Class ContourPlotter

Method Details

• getPlotterDescription

  public 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

• hasReports

  public boolean hasReports()

  Description copied from interface: Plotter

  Indicates whether the drawings produced by this plotter will return general interest report information to upstream plotting code.

  Specified by:

  hasReports in interface Plotter<ContourStyle>

  Overrides:

  hasReports in class AbstractPlotter<ContourStyle>

  Returns:

  true if the plot report may return interesting information

  See Also:

  • Drawing.getReport(Object)

• 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(ConfigMap) method.

  Returns:

  keys used when creating a style for this plotter.

• createStyle

  public ContourStyle 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(DataGeom, DataSpec, S).

  Parameters:

  config - map of style configuration items

  Returns:

  plotter-specific plot style

• createLayer

  public PlotLayer createLayer(DataGeom geom, DataSpec dataSpec, ContourStyle 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(ConfigMap).

  The dataSpec parameter must contain the coordinates defined by this plotter's CoordGroup.

  The pointDataGeom parameter is only used if the CoordGroup.getBasicPositionCount() or CoordGroup.getExtraPositionCount() method from this plotter's CoordGroup return 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

  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
