Returns a dataset containing one series that holds a copy of the (y, z) data from one column (x-index) of the specified dataset.

Usage

From source file:gov.llnl.lc.infiniband.opensm.plugin.gui.chart.PortHeatMapPlotPanel.java

public void stateChanged(ChangeEvent e) {
    // handles both slider events

    if (e.getSource() == PortSlider) {
        //System.err.println("Port Slider is changing " + PortSlider.getValue());
        // this is the vertical slider (moves the horizontal xhair), which moves through ports on vertical axis
        PortXhair.setValue(PortSlider.getValue());
        int xIndex = PortSlider.getValue() - PortSlider.getMinimum();
        if (pHeatMap != null) {
            // extract this slice from the heatmap, and display it
            XYDataset d = HeatMapUtilities.extractRowFromHeatMapDataset(pHeatMap, xIndex, "Y1");
