Examples of org.jfree.chart.axis.NumberAxis

org.jfree.chart.axis.NumberAxis
An axis for displaying numerical data.
If the axis is set up to automatically determine its range to fit the data, you can ensure that the range includes zero (statisticians usually prefer this) by setting the autoRangeIncludesZero flag to true.
The NumberAxis class has a mechanism for automatically selecting a tick unit that is appropriate for the current axis range. This mechanism is an adaptation of code suggested by Laurence Vanhelsuwe.

    if (plot instanceof XYPlot) {
      XYPlot xyPlot = (XYPlot) plot;
      ValueAxis rAxis = xyPlot.getRangeAxis();


      if (rAxis instanceof NumberAxis) {
        NumberAxis nAxis = (NumberAxis) rAxis;
        if (lowerRangeVal != upperRangeVal) {
          nAxis.setLowerBound(lowerRangeVal);
          nAxis.setUpperBound(upperRangeVal);
        }
        nAxis.resizeRange(zoomFactor);
        if (! Double.isNaN(anchorValueR))
          nAxis.centerRange(anchorValueR);
      }


      ValueAxis dAxis = xyPlot.getDomainAxis();
      if (dAxis instanceof DateAxis) {
        ((DateAxis) dAxis).setMinimumDate(lowerDomainValD.getTime());
        ((DateAxis) dAxis).setMaximumDate(upperDomainValD.getTime());
      } else if (dAxis instanceof NumberAxis) {
        NumberAxis nAxis = (NumberAxis) dAxis;
        if (lowerDomainValN != upperDomainValN) {
          nAxis.setRange(lowerDomainValN, upperDomainValN);
        }
        if (! Double.isNaN(anchorValueD))
          nAxis.centerRange(anchorValueD);
      }
    } else if (plot instanceof CategoryPlot) {
      CategoryPlot catPlot = (CategoryPlot) plot;
      NumberAxis axis = (NumberAxis) catPlot.getRangeAxis();
      axis.setLowerBound(lowerRangeVal);
      axis.setUpperBound(upperRangeVal);
      axis.resizeRange(zoomFactor);
    }
