The above example shows you how to create `LineChart` using ChartJs package. 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.
This example shows how to build a multi-axis chart by using <code>yAxisID</code> property and specifying the <code>yAxisID</code> for each column.
For example:
...
"columns"=>array(
"month",
"series1"=>array(
...
"yAxisID" => "y-axis-1",
),
"series2"=>array(
...
"yAxisID" => "y-axis-2",
),
),
"options"=>array(
"scales" => array(
"yAxes" => array(
array(
...
"id" => "y-axis-1"
),
array(
...
"id" => "y-axis-2",
)
)
)
)
...
