java.lang.Object
uk.ac.starlink.ttools.plot.PlotVolume
uk.ac.starlink.ttools.plot.VectorSortPlotVolume

public class VectorSortPlotVolume extends PlotVolume
PlotVolume implementation which accumulates all points to plot and then plots them by drawing, suitable for a vector-like context. Transparency is not renderered.

    • VectorSortPlotVolume

      public VectorSortPlotVolume(Component c, Graphics g, MarkStyle[] styles, double padFactor, int[] padBorders, double fogginess, DataColorTweaker tweaker)
      Constructor.
      Parameters:
      c - component
      g - graphics context
      styles - array of marker styles which may be used to plot
      padFactor - minimum amount of space outside the unit cube in both dimensions - 1 means no extra space
      padBorders - space, additional to padFactor, to be left around the edges of the plot; order is (left,right,bottom,top)
      fogginess - thickness of fog for depth shading
      tweaker - colour adjuster for using auxiliary axis coords

    • plot2d

      public void plot2d(int px, int py, double z, double[] coords, int istyle, boolean showPoint, String label, int nerr, int[] xoffs, int[] yoffs, double[] zerrs)
      Description copied from class: PlotVolume
      Plots an marker and optional associated error values at a given point in graphics coordinates with given additional Z coordinates. Points with greater Z values should obscure points with lesser ones. The ordering of the error points is that required by the ErrorRenderer class.

      Most implementations currently ignore the Z values associated with the error points, and put everything at the depth of the central point, because it's too hard to do otherwise. Does this produce seriously confusing visualisation?

      Specified by:
      plot2d in class PlotVolume
      Parameters:
      px - graphics space X coordinate of the central point
      py - graphics space Y coordinate of the central point
      z - depth of point; a point with a greater z should obscure a point with a lesser one
      coords - original coordinate array; as well as (redundant) x,y,z values it may contain auxiliary axis coordinates
      istyle - index of the style used to plot the point
      showPoint - whether the central point is to be plotted
      label - label for point, or null
      nerr - number of error points, or zero for no errors
      xoffs - nerr-element array of graphics space X coordinates for error points
      yoffs - nerr-element array of graphics space Y coordinates for error points
      zerrs - nerr-element array of depths for error points
    • flush

      public void flush()
      Description copied from class: PlotVolume
      Ensures that all points submitted through the plot method have been painted on the graphics context.
