gchart
GChart is a very simple library that allows you to easily create arrays that are compatible with the Google Charts library. I use it together with Laravel and I am too much of a noob to explain you how to use it otherwise.
Installation
Put this in composer.json
require: "grumpydictator/gchart": "dev-master"
Update the providers-array in app/config/app.php with this:
'Grumpydictator\Gchart\GchartServiceProvider',
Examples
This returns the data used to create the example chart at Google's line chart example:
$chart = App::make('gchart');
$chart->addColumn('Year', 'string');
$chart->addColumn('Sales', 'number');
$chart->addColumn('Expenses', 'number');
// add data:
$chart->addRow('2004', 1000, 400);
$chart->addRow('2005', 1170, 460);
$chart->addRow('2006', 660, 1120);
$chart->addRow('2007', 1030, 540);
$chart->generate();
echo json_encode($chart->getData());
This is roughly the same chart, but it uses date objects for the date:
$chart = App::make('gchart');
$chart->addColumn('Day', 'date');
$chart->addColumn('Pizza slices I ate', 'number');
$chart->addColumn('Beers I drank', 'number');
// add data:
$chart->addRow(new Carbon('2014-05-01'), 3, 1);
$chart->addRow(new Carbon('2014-05-02'), 4, 2);
$chart->addRow(new Carbon('2014-05-03'), 3, 2);
$chart->addRow(new Carbon('2014-05-04'), 6, 3);
$chart->addRow(new Carbon('2014-05-05'), 5, 0);
$chart->addRow(new Carbon('2014-05-06'), 4, 1);
$chart->generate();
echo json_encode($chart->getData());
