The above example shows you how to create ComboChart
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 combo chart using the type
property and specifying the type
for each column.
If no type property, type will be bar chart
For example:
...
'columns' => array(
"month",
"Dataset 1" => array(
...
"config" => array(
"type" => "line",
)
),
"Dataset 2" => array(
...
),
"Dataset 3" => array(
...
)
)
...
