VectorSortPlotVolume
public VectorSortPlotVolume(Component c, Graphics g, MarkStyle[] styles, double padFactor, int[] padBorders, double fogginess, DataColorTweaker tweaker) Constructor.- Parameters:
c
- componentg
- graphics contextstyles
- array of marker styles which may be used to plotpadFactor
- minimum amount of space outside the unit cube in both dimensions - 1 means no extra spacepadBorders
- 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 shadingtweaker
- 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 theErrorRenderer
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:

- Parameters:
px
- graphics space X coordinate of the central pointpy
- graphics space Y coordinate of the central pointz
- depth of point; a point with a greaterz
should obscure a point with a lesser onecoords
- original coordinate array; as well as (redundant) x,y,z values it may contain auxiliary axis coordinatesistyle
- index of the style used to plot the pointshowPoint
- whether the central point is to be plottedlabel
- label for point, or nullnerr
- number of error points, or zero for no errorsxoffs
