Class PixOutliner

Method Details

• calculateBinPlan

  public Object calculateBinPlan(Surface surface, DataGeom geom, Map<AuxScale,Span> auxRanges, DataStore dataStore, DataSpec dataSpec, Object[] knownPlans)

  Description copied from interface: Outliner

  Calculates an opaque object which contains the drawing of this outliner represented as an array of bins, one per pixel. To make sense of the returned object, use the Outliner.getBinCounts(Object) and Outliner.getPointCount(Object) methods.

  If one of the supplied knowPlans fits the bill, it will be returned without further calculation.

  Specified by:

  calculateBinPlan in interface Outliner

  Parameters:

  surface - plot surface

  geom - coordinate geometry

  auxRanges - map of scale information required for plot

  dataStore - data storage

  dataSpec - coordinate specification

  knownPlans - list of existing plans

  Returns:

  bin plan, either newly calculated or taken from knownPlans

• getBinCounts

  public int[] getBinCounts(Object binPlan)

  Description copied from interface: Outliner

  Returns the bin contents for a given bin plan produced by this object.

  Specified by:

  getBinCounts in interface Outliner

  Parameters:

  binPlan - bin plan returned from calculateBinPlan

  Returns:

  array of counts, one element per bin

• getPointCount

  public long getPointCount(Object binPlan)

  Description copied from interface: Outliner

  Returns the number of data positions which contributed to a BinPlan generated by this object. This may or may not be the same as the sum of the pixel counts in the binCounts array; if each data position might contribute multiple pixel hits, the numbers will not be the same.

  Specified by:

  getPointCount in interface Outliner

  Parameters:

  binPlan - bin plan returned from calculateBinPlan

  Returns:

  number of data positions in plan

• getReport

  public ReportMap getReport(Object binPlan)

  Description copied from interface: Outliner

  Obtains information associated with the plot.

  Specified by:

  getReport in interface Outliner

  Parameters:

  binPlan - bin plan returned from calculateBinPlan

  Returns:

  report map, or null for no reports
