Thank you, this helped me a lot.
Today i come with another question regarding your awesome charts.
Please have a look at https://jsfiddle.net/x10Lncup/ and tell me, why the chart doesn´t draw the line? In original, the data comes out of a database and is pushed into an array which i give to the datapoints:
dataPoints: <?php echo json_encode($humi, JSON_NUMERIC_CHECK); ?>
The values seems to be recognized by the chart, the numbers at the yAxis are already in place.
Thank you for your help.
