Slice Visibility Threshold
The above example shows you how to create `PieChart` 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:
...
$data = [
['Pizza', 'Populartiy'],
['Pepperoni', 33],
['Hawaiian', 26],
['Mushroom', 22],
['Sausage', 10], // Below limit.
['Anchovies', 9] // Below limit.
];
"options" => array(
"sliceVisibilityThreshold" => .2
)
