Chart PHP Class Overview

The Kendo UI Chart for PHP is a server-side wrapper for the Kendo UI Chart widget.

Getting Started

The Basics

There are two ways to bind a Kendo UI Chart for PHP:

  • Locally—Local binding binds the Chart to a PHP array.
  • Remotely—During remote binding the Chart makes AJAX requests and is bound to the JSON result.

Configuration

Below are listed the steps for you to follow when configuring the Kendo UI Chart for local binding.

Step 1 Make sure you followed all the steps from the introductory article on Telerik UI for PHP—include the autoloader, JavaScript, and CSS files.

Step 2 Create an array to which the Chart will be bound.

    <?php
    $data = array(
        array('name' => 'John Doe', 'age' => 32),
        array('name' => 'Jane Doe', 'age' => 29)
    );
    ?>

Step 3 Create a data source and set its data.

    <?php
    $dataSource = new \Kendo\Data\DataSource();
    $dataSource->data($data);
    ?>

Step 4 Create a Chart, configure its series, categoryAxis and set its DataSource.

    <?php
    $ageSeries = new \Kendo\Dataviz\UI\ChartSeriesItem();
    $ageSeries->field('age');

    $categoryAxis = new \Kendo\Dataviz\UI\ChartCategoryAxisItem();
    $categoryAxis->field('name');

    $chart = new \Kendo\Dataviz\UI\Chart('chart');
    $chart->addSeriesItem($ageSeries)
          ->addCategoryAxisItem($categoryAxis)
          ->dataSource($dataSource);
    ?>

Step 5 Output the Chart by echoing the result of the render method.

    <?php
    echo $chart->render();
    ?>

Event Handling

You can subscribe to all Chart events.

Specify Function Names

The example below demonstrates how to subscribe for events by specifying a JavaScript function name.

    <?php
    $chart = new \Kendo\Dataviz\UI\Chart('chart');

    // The 'chart_dataBound' JavaScript function will handle the 'dataBound' event of the chart
    $chart->dataBound('chart_dataBound');

    echo $chart->render();
    ?>
    <script>
    function chart_dataBound() {
        // Handle the dataBound event
    }
    </script>

Provide Inline Code

The example below demonstrates how to provide inline JavaScript code.

    <?php
    $chart = new \Kendo\Dataviz\UI\Chart('chart');

    // Provide inline JavaScript code that will handle the 'dataBound' event of the chart
    $chart->dataBound('function() { /* Handle the dataBound event */ }');

    echo $chart->render();
    ?>

Reference

Client-Side Instances

You can reference the client-side Kendo UI Chart instance via jQuery.data(). Once a reference is established, use the Chart API to control its behavior.

    <?php
    $chart = new \Kendo\Dataviz\UI\Chart('chart');
    echo $chart->render();
    ?>
    <script>
    $(function() {
        // The constructor parameter is used as the 'id' HTML attribute of the chart
        var chart = $("#chart").data("kendoChart")
    });
    </script>
