Examples of plotter.xy.DefaultCompressor

plotter.xy.DefaultCompressor
Default implementation of {@link Compressor}. Optimized for mostly continuous data. Works best when, on the small scale, the data is either non-increasing or non-decreasing. @author Adam Crume

    xAxis.setTickMarkCalculator(new TimeTickMarkCalculator());
    xAxis.setFormat(new DateNumberFormat(new SimpleDateFormat("yyyy-MM-dd\nHH:mm:ss.SSS")));


    final LinearXYPlotLine line = new LinearXYPlotLine(xAxis, yAxis, XYDimension.X);
    line.setForeground(Color.white);
    final CompressingXYDataset d = new CompressingXYDataset(line, new DefaultCompressor());
    d.setTruncationPoint(0);
    d.setXData(line.getXData());
    d.setYData(line.getYData());
    final XYMarkerLine marker = new XYMarkerLine(xAxis, 60);
    marker.setForeground(Color.yellow);
