This is a class that transforms PHP arrays of series data into a JSON format that Flot can understand. It supports line/bar charts, pie charts, horizontal/vertical orientation, and time series data. It also supports single or multiple series.

To load as a service in a Symfony bundle, see my jasonroman/flot-bundle package.

Usage

// convert to Flot JSON data from PHP arrays
use JasonRoman\Flot\Flot;

$flot = new Flot;

$flotData = $flot->convert($data);
$flotData = $flot->convert($data, 'horizontal');
$flotData = $flot->convert($data, 'vertical', $datetime = true);
$flotData = $flot->convert($pieData);

See the comments in the class for more examples of the various forms of array $data that can be passed to the convert() function.
