Bar Charts Side By Side - oliverwatkins/Iceberg-Charts GitHub Wiki

Bar charts can also hold multiple series.

We can define a list of DataPointBar objects and add them to an ArrayList.

We can then add these values (which represent one multi-bar datapoint) to something called a DataPointMultiBar. In the constructor we can say if we want the data side-by-side or stacked :

DataPointMultiBar mb1 = new DataPointMultiBar(values, "2007", MultiBarMode.SIDE_BY_SIDE);

Once we have a number of these elements we can add them to an array or list and then pass them into an XYDataSeries. The XYDataSeries also needs to a define a UIPoint for this special data type, namely, a UIPointMultiBarSideBySide. The 70 represents the percentage between points where the bars fill up to :

XYDataSeries series = new XYDataSeries(multiBarList, 
      new UIPointMultiBarSideBySide(70), null, "1994");
