I am trying to plot a graph in codeigniter framework. I have a javascript code for plotting graph. The graph is plotting with respect to database values.

I write the php code for fetching data from the database and create a controller for read the model value. but i don't know how to to sent that fetched value in the controller to the javascript in codeigniter framework. here i am attaching the controller code.

$this->load->model('piechart');
        $res['h'] = $this->piechart->piechart();

$res containing the value of graph.

in your controller just do this: echo json_encode($res); – Saranya Rajendran Jan 22 '18 at 11:02
that will direct to the js file? – user9133196 Jan 22 '18 at 11:08
there must be a function to display the piechart,we need to call a function in pidiagram.js – Saranya Rajendran Jan 22 '18 at 11:39
