From source file:edu.fullerton.viewerplugin.PluginSupport.java

public static int scaleRange(TimeSeriesCollection mtds, Double miny, Double maxy) {
    int exp = PluginSupport.getExp(miny, maxy);
    double scale = Math.pow(10, exp);
    for (Iterator it = mtds.getSeries().iterator(); it.hasNext();) {
        TimeSeries ds = (TimeSeries) it.next();
        for (int item = 0; item < ds.getItemCount(); item++) {
            TimeSeriesDataItem dataItem = ds.getDataItem(item);
            RegularTimePeriod period = dataItem.getPeriod();

            double y = dataItem.getValue().doubleValue();
            y *= scale;//from w ww.j  ava 2  s.com
            ds.update(period, y);
