Stacked Bars

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>
