Updating a BoxChart by setting the BoxSeries data to an empty list causes an IndexOutOfBoundsException to be thrown.

[hogan-deng]

Describe the bug
If a BoxChart is updated by calling replaceData with an empty list on a BoxSeries obtained from chart.addSeries, the internal sanityCheck is bypassed, resulting in an IndexOutOfBoundsException.

To Reproduce
The following chart code can reproduce the issue:

public class OutOfBounds {
  public static void main(String[] args) throws ParseException {
    BoxChart chart = getBoxChart();
    new SwingWrapper(chart).displayChart();
  }

  public static BoxChart getBoxChart() {
    BoxChart chart = new BoxChartBuilder()
      .title("box plot demo")
      .xAxisTitle("X")
      .yAxisTitle("Y")
      .build();

    BoxSeries boxSeries = chart.addSeries("test", Arrays.asList(1, 2));
    boxSeries.replaceData(Arrays.asList());

    return chart;
  }
}

Expected behavior
The program should either run normally or issue a proper warning.
