Chart.js is a great library by nnick which allows you to easily add rich visual graphs to your project. However, since it is a JS library, using it in PHP might get a bit tedious. You can have as many charts as you wish. Generated JS code is namespaced so it doesn't clash with code from other Chart.js instances.

Here to change that is Chart.js for PHP. It is fully compatible with Chart.js 1.x (will be updated for 2.x soon).

1. Clone this repository and place the contents of the src folder anywhere in your PHP project.

2. include the files in your PHP project.

3. Place chart.min.js anywhere in your project.

4. Place this into the page where you want to display charts:

   <script src="path/to/chart.min.js"></script>

For creating a line chart, you need two arrays: One containing the labels of the chart (x-axis) and one containing the datasets. A datasets consist of a label, the values and a theme.

1. Create a theme for your dataset:

   $theme = new CommonChartTheme($fillColor, $strokeColor, $pointColor, $pointStrokeColor, $pointHighlightFull, $pointHighlightStroke);

   Alternatively, use one of the default ones:

   $theme = CommonChartTheme::createDefault();

2. Create a dataset and apply the theme:

   $dataset = new CommonChartDataset('Example Data', [ 50, 100, 25, 42 ], $theme);

3. Create the chart:

   $chart = new LineChart([ 'Today', 'Today+1', 'Today+2', 'Today+3' ], [ $dataset ], []);

   You can provide options as a third parameter. Use the options provided by Chart.js.

4. Create output:

   echo $chart->__toJS($customID = uniqid(), $responsive = true, $width = Chart::DEFAULT_WIDTH, $height = Chart::DEFAULT_HEIGHT);

1. Create data:

   $data = [
       new PieChartData('Data 1', 13, '#292c34', '#fff'),
       new PieChartData('Data 2', 42, '#1177aa', '#fff')
   ];

2. Create the chart:

   $chart = new PieChart($data, []);

   You can provide options as a second parameter. Use the options provided by Chart.js.

3. Create output:

   echo $chart->__toJS($customID = uniqid(), $responsive = true, $width = Chart::DEFAULT_WIDTH, $height = Chart::DEFAULT_HEIGHT);

There are only 2 major chart types. Here's how they depend one each other:

• CommonChart
  • BarChart
  • LineChart
• PieChart
  • DoughnutChart

Every CommonChart works like any other CommonChart. PieChart and DoughnutChart are completely compatible (you can even use PieChartData with DoughnutChart but for semantics sake, DoughnutChartData is provided).

This library supports Chart.js 1.x only. You need at least PHP 5.4 because people, move on.

Contributions are welcome. Issue pull requests when you have improvements or fixes.
