I'm using http://canvasjs.com/ to create a bar graph. So far, when the user clicks 'submit' the entered numbers are displayed on a graph http://jsfiddle.net/jx9sJ/5/ .
Now, I'm trying to change it. So the entered numbers are sent to ajax, calculations done, & then encoded using json_encode($total);
I'm struggling to create the graph from the values, which are in json_encode
. How can this be done?
Code so far
$fortot2 = 5;
$fortot3 = 2;
if (is_numeric($numwelds) && is_numeric($numconwelds))
{
$total['tot1'] = $numwelds + $numconwelds + $fortot3 ;
$total['tot2'] = $numwelds + $numconwelds + $fortot2 ;
$total['tot3'] = $numwelds + $numconwelds;
$response = json_encode($total);
header("Content-Type: application/json");
echo $response;
exit;
}
Using print_r json_encode($total) is structured as
Array ( [tot1] => 3 [tot2] => 5 [tot3] => 1 )
