Class WrapperPlotLayer

Method Details

• getPlotter

  public Plotter<?> getPlotter()

  Description copied from interface: PlotLayer

  Returns the plotter that generated this layer. Used to help determine whether this layer is the same as another one.

  Specified by:

  getPlotter in interface PlotLayer

  Returns:

  parent plotter

• getStyle

  public Style getStyle()

  Description copied from interface: PlotLayer

  Returns the plot style used by this layer.

  Specified by:

  getStyle in interface PlotLayer

  Returns:

  plot style

• getDataGeom

  public DataGeom getDataGeom()

  Description copied from interface: PlotLayer

  Returns the data geometry used by this layer. This can be used in conjunction with the DataSpec to determine the base positions in data space of what has been plotted. Depending on the nature of the returned object, these positions may be actual points in the data space, or some higher-dimensional object. If null is returned, no such information is available.

  Specified by:

  getDataGeom in interface PlotLayer

  Returns:

  data geom, or null

• getDataSpec

  public DataSpec getDataSpec()

  Description copied from interface: PlotLayer

  Returns the data spec that defines the data used by this layer. May be null if no tabular data is required.

  Specified by:

  getDataSpec in interface PlotLayer

  Returns:

  data spec, or null

• extendCoordinateRanges

  public void extendCoordinateRanges(Range[] ranges, Scale[] scales, DataStore dataStore)

  Description copied from interface: PlotLayer

  Gives this layer a chance to adjust the coordinate ranges assembled during data ranging. Supplied is an array of range objects, each corresponding to one of the data position dimensions (it has surface.getDataDimCount elements). If this layer needs to adjust these ranges beyond what is implied by the result of getDataGeom, it may be done here. The implementation may or may not need to acquire a tuple sequence from the supplied dataStore.

  An array of flags indicating whether each range corresponds to a logarithmic axis is also supplied (same number of eements as ranges). This may or may not make physical sense for a given case - if in doubt, false elements are given.

  In many cases (especially for point-plotting type layers) the implementation of this method will be a no-operation.

  Specified by:

  extendCoordinateRanges in interface PlotLayer

  Parameters:

  ranges - array of data space dimension ranges, may be adjusted

  scales - array of axis scalings corresponding to ranges array

  dataStore - data storage object

• getAuxRangers

  public Map<AuxScale, AuxReader> getAuxRangers()

  Description copied from interface: PlotLayer

  Returns a map indicating what additional ranging needs to be done on the input data before this layer can be drawn. Each key of the returned map represents a range that needs to be determined; such keys may be shared between layers in the same plot. The corresponding value is an object that can be used to (help) determine the range from the data.

  Note that ranging of the plot surface axes themselves is handled elsewhere.

  Specified by:

  getAuxRangers in interface PlotLayer

  Returns:

  range scales required for plot

• getOpt

  public LayerOpt getOpt()

  Description copied from interface: PlotLayer

  Returns an object that describes some facts about how this layer draws itself used for rendering.

  Specified by:

  getOpt in interface PlotLayer

  Returns:

  layer option flags

• createDrawing

  public Drawing createDrawing(Surface surface, Map<AuxScale,Span> auxSpans, PaperType paperType)

  Description copied from interface: PlotLayer

  Creates a drawing from this layer that can contribute to a user-visible plot. The auxSpans parameter is a map that must contain a Span object for (at least) every scale returned as a key of the map returned by PlotLayer.getAuxRangers().

  If this layer is unable to draw to the given paper type, an unchecked exception may be thrown. In general it's up to the plotting system to ensure that layers are only painted on suitable paper types. This logic is in PlotType.

  Specified by:

  createDrawing in interface PlotLayer

  Parameters:

  surface - plot surface

  auxSpans - range information

  paperType - rendering object
