Symfony2中Highcharts的JSON数据与ObHighchartsBundle

但我想使用json数据，例如在文件中——我如何实现这一点

提前谢谢

控制器：

public function chartAction()
{
            $series = array(
            array(
                "name" => "Input",
                "data" => $this->getArray()
            ),
            array(
                "name" => "Output",
                "data" => $this->getArray())
        );

        $ob->chart->renderTo('datachart');  // The #id of the div where to render the chart
        $ob->chart->backgroundColor('transparent');
        $ob->title->text("Hello Title");

        $ob->xAxis->type('datetime');
        $ob->chart->zoomType("x");

        $ob->xAxis->title(array('text' => "Horizontal axis title"));
        $ob->yAxis->title(array('text' => "Vertical axis title"));
        $ob->series($series);

        return $this->render(':charts:charts.html.twig', array(
            'chart' => $ob
        ));
}
