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 logarithmic y-axis values using the type property.
For example:
...
"yAxes" => array(
array(
...
"type" => "logarithmic"
)
)
...
<?php
require_once "../../../load.koolreport.php";
require_once "MyReport.php";
$report = new MyReport;
$report->run();
// $report->render();
?>
<?php
if (isset($_POST['command']) && $_POST['command'] === 'randomizeData') {
?>
<div id='report_render'>
<?php
$report->render();
?>
</div>
<?php
exit();
}
?>
<?php
if (!isset($_POST['command'])) {
?>
<div id='report_render'>
<?php
$report->render();
?>
</div>
<?php
}
?>
