    Thanks @Suyash singh,
    My chart have the correct format chart but now my chart is static doesn’t accept new data, I´m using the same code so this function should works, I fixed that deleting the next code: ` dataLength = result.length;sortDataPoints(data, ‘x’);value = value + deltaX; value2 = value2 + deltaY;valor = CanvasJS.formatDate(new Date(value), “YYYY-MM-DD hh:mm:ss:fff”) + ” HR :”+ value2 + ” 25mm/s 10mm/mv”;chart.options.data[0].legendText = valor;
    But how you suppose it’s necessary to show the legend text with the values coming, If you know how I can do this works again I will be very grateful.

    Hi Again @Vishwas R,
    I leave you my code jsfiddle and some examples of my data_ecg4.php file that I use :

    Hi @Vishwas R,
    Thank you for your help ,I leave you my code example jsFiddle I saw some examples that you gave me in the tutorial but this still working bad, I added in your code this part “setTimeout(updateEcg,updateInterval); ” .
    I share you a video when I show you how it´s working my code ECG chart.
    Any comment or suggestion in my code is perfect for me , thanks in advice.

    in reply to: Line Graph Point Connection Bug #14195

    @Vishwas R ,Thank you for replay question.
    I added the sort before the chart,render() , I leave you the new code :
    function updateEcg() {
    $.getJSON(“/data_ecg4.php”, function (result) {
    if (dataLength !== result.length) {
    for (var i = dataLength; i < result.length; i++) {
    data.push({
    x: parseInt(result[i].valuex),
    y: parseFloat(result[i].valuey),
    });
    if (data.length > 478) {
    data.shift(); }}
    dataLength = result.length;
    data.sort((a,b)=>a-b);
    chart.render();} });
    Is correct my idea? or I need to change something? , thanks in advice.

    in reply to: Line Graph Point Connection Bug #14190

    Hi @Vishwas R, I use this code to update my chart:
    function updateEcg() {
    $.getJSON(“/data_ecg.php”, function (result) {
    if (dataLength !== result.length) {
    for (var i = dataLength; i < result.length; i++) {
    data.push({
    x: parseInt(result[i].valuex),
    y: parseFloat(result[i].valuey)});
    if (data.length > 478) {
    data.shift(); }}
    dataLength = result.length;
    chart.render();}});}
    How you can see I parse my valueX to Int , and yes some of my X values are not in order, I attach you an image ( data order ) where you can see that the counter is not having order when it is inserting. Do you know how can I sort my X values to have a good chart?
