The above example shows you how to create `SteppedAreaChart` using built-in Google Charts. In this example, for purpose of chart demonstration only, we do use mock-up data from array. As you can see, the KoolReport's widget in general support dataSource could be DataStore, Process, DataSource or even simple array.
For example:
...
"options"=>array(
"isStacked"=>true // 'relative' is 1000% stacked
)
