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.

//          numberAxis.setTickUnit(new NumberTickUnit(axisRange/tickCount));
//      }
//    }
    if(axis instanceof NumberAxis)
    {
      NumberAxis numberAxis = (NumberAxis)axis;
      int axisRange = (int)numberAxis.getRange().getLength();
      if(axisRange > 0)
      {
        if(tickInterval != null)
        {
          if(numberAxis.getNumberFormatOverride() != null)
          {
            numberAxis.setTickUnit(new NumberTickUnit(tickInterval.doubleValue(), numberAxis.getNumberFormatOverride()));
          }
          else
          {
            numberAxis.setTickUnit(new NumberTickUnit(tickInterval.doubleValue()));
          }
        }
        else if (tickCount != null)
        {
          int newTickUnitSize = axisRange / tickCount.intValue();
          if(newTickUnitSize > numberAxis.getTickUnit().getSize())
          {
            int tickUnitSize = newTickUnitSize;
      
            //preferably multiple of 5 values should be used as tick units lengths:
            int i = 1;
            while(tickUnitSize > 9)
            {
              tickUnitSize /= 10;
              i *= 10;
            }
            tickUnitSize *= i;
            newTickUnitSize = tickUnitSize + i/2;
      
            if(newTickUnitSize > 0 && axisRange / newTickUnitSize > tickCount.intValue())
            {
              newTickUnitSize += i / 2;
            }
            if(numberAxis.getNumberFormatOverride() != null)
            {
              numberAxis.setTickUnit(new NumberTickUnit(newTickUnitSize, numberAxis.getNumberFormatOverride()));
            }
