I am having difficulties to get the data received from PHP script and set it into the Gauge graph. I am getting the json result correctly, just do not know how to set it to the right Highchart gauge variables (gaugeOptions).
I'd like to put in #container-C_2 the returned values from PHP, so configure the min, max and set the value on the gauge graph. strong text I think In the $.getJSON() body I need to call $('#container-C_2').highcharts( with some arguments, but don't know how..
Can someone help me here?
Many thanks.
PHP
$result = array();
$result['name'][0] = 'A';
//--some values
$result['min'][] = 10;
$result['max'][] = 50;
$result['val'][] = 20;
$json = array();
array_push($json,$result);
print json_encode($json);
