Using the StackedAreaChart
The StackedAreaChart is to the AreaChart what the StackedBarChart is to the BarChart . Rather than showing
individual areas, the StackedAreaChart always shows the sum of the values in a specific category.
Changing an AreaChart into a StackedAreaChart only requires the change of one line of code and the
appropriate import statement.
AreaChart areaChart = new AreaChart(xAxis, yAxis);
must be replaced with
StackedAreaChart areaChart = new StackedAreaChart(xAxis, yAxis);
Applying this change and running the application results in a graph like the one in Figure 8-15 .
