The above example shows you how to create `LineChart` 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(
        "curveType" => 'function',
        ...
    )
