Description

Create charts with ChartJS through PHP. You make the chart in PHP code and serialize it to Javascript. In Javascript you create the chart by deserialize the output of the PHP Chart class.

The Manager class holds the graphs and is responsible for rendering.

$("canvas[id^='chart_']").each(function(idx, el) {
	new Chart(
		$(el).attr('id'), 
		$.parseJSON(atob($(el).data('chart')))
	);
});

If you use Laravel. Simply register the Manager class in the AppServiceProvider.

public function register()
{
	$this->app->singleton('charts', \Diagro\Chart\Manager::class);
}

In a blade view:

{{ app('charts')->render('chart_id') }}

Or register a stringable blade like:

Blade::stringable(\Diagro\Chart\Chart::class, function($chart) {
    return app('charts')->render($chart->id);
});

Example:

$chart = new Chart('messages_per_time', Chart::TYPE_BAR);
$chart->labels = array_keys($per_datetime);
$chart->datasets[0] = new \Diagro\Chart\Datasets\Bar('Aantal per tijdstip');
$chart->datasets[0]->data = array_values($per_datetime);
$chart->datasets[0]->background_color = [
	new \Diagro\Chart\Color\RGBA(255,99,132,0.2),
	new \Diagro\Chart\Color\RGBA(54,162,235,0.2)
];
$chart->datasets[0]->border_color = [
	new \Diagro\Chart\Color\RGBA(255,99,132,1),
	new \Diagro\Chart\Color\RGBA(54,162,235,1)
];
$chart->datasets[0]->border_width = 1;

$chart->options->plugins->legend->display = false;
