uk.ac.starlink.ttools.plot.BitmapSortPlotVolume
public class BitmapSortPlotVolume
PlotVolume implementation which accumulates all points to plot and then draws them in a way suitable for a bitmap-type context. Transparency is rendered. Points with and without error bars can be plotted.

PlotVolume
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?
