Method Detail

plotMarker

public void plotMarker(SVGPlot plot,
              Element parent,
              double x,
              double y,
              int style,
              double size)

Draw an marker used in scatter plots. If you intend to use the markers multiple times, you should consider using the useMarker(de.lmu.ifi.dbs.elki.visualization.svg.SVGPlot, org.w3c.dom.Element, double, double, int, double) method instead, which exploits the SVG features of symbol definition and use

Parameters:

plot - containing plot

parent - parent node

x - position

y - position

style - marker style (enumerated)

size - size

plotGray

protected void plotGray(SVGPlot plot,
            Element parent,
            double x,
            double y,
            double size)

Plot a replacement marker when an object is to be plotted as "disabled", usually gray.

Parameters:

plot - Plot to draw to

parent - Parent element

x - X position

y - Y position

size - Size

plotUncolored

protected void plotUncolored(SVGPlot plot,
                 Element parent,
                 double x,
                 double y,
                 double size)

Plot a replacement marker when no color is set; usually black

Parameters:

plot - Plot to draw to

parent - Parent element

x - X position

y - Y position

size - Size

useMarker

public Element useMarker(SVGPlot plot,
                Element parent,
                double x,
                double y,
                int style,
                double size)

Description copied from interface: MarkerLibrary

Insert a marker at the given coordinates. Markers will be defined in the defs part of the document, and then SVG-"use"d at the given coordinates. This supposedly is more efficient and significantly reduces file size. Symbols will be named "s0", "s1" etc.; these names must not be used by other elements in the SVG document!

Specified by:

useMarker in interface MarkerLibrary

Parameters:

plot - Plot to draw on

parent - parent node

x - coordinate

y - coordinate

style - style (enumerated)

size - size

Returns:

Element node generated.
