    i think your data doesnt contain any usefull. Do you test with php echo or js alert the output?

    let $arr your array from SQL, then you give canvasJS the data in a new array row with: json_encode($arr) see line two
    on line thre an example how to look for usefull data. Good luck!

    window.onload = function () {
    var row = <?php echo json_encode($arr) ?>;
    // alert(row[1][‘datum’] );

    var data = [];
    var dataSeries = {
    type: “spline”,
    fillOpacity: .0,
    lineThickness: 6,
    //color: “rgba(192,192,192,0.9)”,
    yValueFormatString: “#0.# °C”,
    toolTipContent: ” <span \”style=’color:#4F81BC’ align=’middle’\”><h2>{x}</h2></span><br><h2>{y}</h2>”, };
    var dataPoints = [];

    for (var i = 0; i < <?php echo $rows+1?>; i += 1) {
    //for (var i = 0; i < <?=$rows?>; i += 1) {
    //y += Math.round(Math.random() * 10 – 5);
    y=parseFloat(row[i][‘temperatur’]);

    x=new Date(row[i][‘datum’]);
    dataPoints.push({
    x: x,
    y: y
    });
    }
    dataSeries.dataPoints = dataPoints;
    data.push(dataSeries);

    and so on…
