Example 81 with Stroke

use of java.awt.Stroke in project knime-core by knime.

the class DendrogramDrawingPane method paintContent.

/**
 * Paints a dendrogram such that the leaf nodes are painted at the border
 * (with distance 0) and on the nominal x axis and the cluster nodes are
 * drawn with increasing distance to the top (that is the distance is
 * plotted on the y axis). Each cluster node has exactly two subnodes,
 * a horizontal line on the height of the distance between these two
 * subnodes and two vertical lines from the end points of the
 * horizontal line to the subnodes.
 *
 * <p>
 * Hilited (sub)nodes are colored with the hilite color and hilited and
 * selected clusteres are visualized through color and emphasized line
 * thickness.
