  • Constructor Details

    • SimpleDecalPlotter

      protected SimpleDecalPlotter(String name, Icon icon, CoordGroup cgrp, boolean hasReports)
      Constructor.
      Parameters:
      name - plotter name
      icon - plotter icon
      cgrp - coordinate group
      hasReports - whether plot reports are generated

  • Method Details

    • createLayer

      public PlotLayer createLayer(DataGeom geom, DataSpec dataSpec, S 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

    • getLayerOpt

      protected abstract LayerOpt getLayerOpt(S style)
      Indicates the layer optimisation options that apply to a given style.
      Parameters:
      style - plot style
      Returns:
      layer options

    • paintData2D

      protected abstract void paintData2D(Surface surface, DataStore dataStore, DataGeom geom, DataSpec dataSpec, S style, Graphics g, PaperType paperType)
      Called during Decal painting to perform the actual plot.
      Parameters:
      surface - plot surface
      dataStore - data storage object
      geom - data geometry
      style - plot style
      g - graphics context
      paperType - paper type
