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(
...
"crosshair" => [
"color" => '#000',
"trigger" => 'selection'
]
)
