The above example shows you how to create BarChart 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:
...
"options"=>array(
"isStacked"=>true,
...
)
<?php
require_once "../../../../load.koolreport.php";
require_once "MyReport.php";
$report = new MyReport;
$report->run()->render();
<?php
require_once "../../../../load.koolreport.php";
class MyReport extends \koolreport\KoolReport
{
}
<?php
use \koolreport\widgets\google\BarChart;
$data = [
['City', '2010 Population', '2000 Population'],
['New York City, NY', 8175000, 8008000],
['Los Angeles, CA', 3792000, 3694000],
['Chicago, IL', 2695000, 2896000],
['Houston, TX', 2099000, 1953000],
['Philadelphia, PA', 1526000, 1517000]
];
?>
<div class="report-content">
<div class="text-center">
<h1>Stacked Bars</h1>
</div>
<div style="margin-bottom:50px;">
<?php
BarChart::create(array(
"dataSource" => $data,
"columns" => array(
'City',
'2010 Population',
'2000 Population'
),
"options" => array(
"title" => "Population of Largest U.S. Cities",
"isStacked" => true,
"hAxis" => [
"title" => 'Total Population',
"minValue" => 0,
],
"vAxis" => [
"title" => 'City'
]
)
));
?>
</div>
</div>
