the class HierarchicalClusterNodeView method modelChanged.

    ((BasicDrawingPane) m_distancePlotter.getDrawingPane()).clearPlot();
    m_distancePlotter.addLine(distanceTable, 0, 1, Color.BLACK, new BasicStroke(m_thickness));
    // m_distancePlotter.getXAxis().getCoordinate().setPolicy(
    // DescendingNumericTickPolicyStrategy.getInstance());

    m_dendroPlotter.updatePaintModel();
}

Example 2 with DendrogramNode

use of org.knime.base.node.viz.plotter.dendrogram.DendrogramNode in project knime-core by knime.

the class ClusterNode method getDataRows.

/**
 * Puts all data rows of a node in a vector if the node is a leaf. Otherwise
 * the method is invoked with the nodes child nodes. This is a recursive
 * tree traversing method.
 *
 * @param clusterNode the node to get the data rows from.
 * @param rowVector the vector to store the found data rows in.
 */
private void getDataRows(final DendrogramNode clusterNode, final List<DataRow> rowVector) {
    // rekursives auslesen aller data rows
    DendrogramNode subNode1 = clusterNode.getFirstSubnode();
    DendrogramNode subNode2 = clusterNode.getSecondSubnode();
    if (subNode1.isLeaf()) {
        rowVector.add(subNode1.getLeafDataPoint());
    } else {
