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 line chart with the y-axis range set using the min and max properties.
For example:
...
"scales" => array(
"yAxes" => array(
array(
"ticks" => array(
"min" => 10,
"max" => 50,
)
)
)
)
...
<?php
require_once "../../../load.koolreport.php";
require_once "MyReport.php";
$report = new MyReport;
$report->run();
$report->render();
?>
