Chart.js-PHP

A PHP wrapper for nnnick/Chart.js

When using a lot of charts in a project, we need to write a lot of code.

This small PHP wrapper use data-attributes to load chart with Chart.js with less code.

Charts implemented

Line
Bar
Radar
Polar Area
Pie & Doughnut

How to use

Include Chart.js and chart.js-php.js before the end of your body (change src according to your project)

<html>
  <body>
    <!-- Your awesome project comes here -->
    
    <!-- And here are Chart.js and Chart.js-PHP -->
    <script src="js/Chart.js"></script>
    <script src="js/chart.js-php.js"></script>
  </body>
</html>

Load ChartJS-PHP classes or use an autoloader

require 'class/ChartJS.php';
require 'class/ChartJS_Line.php';

Then, create your charts using PHP.

$Line = new ChartJS_Line('example', 500, 500);
$Line->addLine(array(1, 2, 3, 4));
$Line->addLabels(array('A label', 'Another', 'Another one', 'The last one'));

// Echo your line
echo $Line;
?>

Finally, load these charts with a small piece of javascript when your document is ready

// Pure JS document.ready
(function() {
  loadChartJsPhp();
})();

Advanced use (colors, etc)

Have a look at the wiki (soon)

$Line->addLabels(array('A label', 'Another', 'Another one', 'The last one'));
