  • in reply to: Cant update Dynamic Chart via AJax JSON for Candle Stick #16169

    Thank you Indranil!

    What if we are getting the entire array of data again instead of just one more stick info at a time? Keep in mind I am trying to make a Dynamic candle stick chart that renders stock prices.

    1. Should we clear the chart? right now it plots the data right on top of the last data?
    2. I tried (and it didn’t work) in the ajax

    chart.options.data[0].dps = data;
    chart.render();
    3. I also tried to set dps to [] reset the array to clear the chart to no avail.

    Let me know,
    thanks

    and here is the code that is trying to refresh the graph, dps is global and so is chart

    var dps;
    var chart;

    function getValuesChart() {

    var scriptUrl = “controller.php?route=graph”;
    $.ajax({
    url: scriptUrl,
    type: ‘get’,
    dataType: ‘text’,
    async: false,
    success: function(data) {
    dps = data;
    }
    });

    chart.render();
    }

    in reply to: Cant update Dynamic Chart via AJax JSON for Candle Stick #16145

    I have tried the following strings (returned from ajax call):

    [{“x”:0,”y”:[3879.0850, 3875.1865,3875.1860,3875.1865]},{“x”: 1,”y”:[3875.1865, 3879.0850,3879.0800,3879.0850]},{“x”: 2,”y”:[3879.0850, 3882.9883,3882.9881,3882.9883]},{“x”: 3,”y”:[3882.9883, 3883.7885,3883.7883,3883.7885]},{“x”: 4,”y”:[3883.7885, 3884.6880,3878.8861,3884.6880]},{“x”: 5,”y”:[3884.6880, 3881.6886,3880.9860,3881.6886]},{“x”: 6,”y”:[3881.6886, 3880.9860,3880.9860,3880.9860]},{“x”: 7,”y”:[3880.9860, 3881.1866,3878.3853,3881.1866]},{“x”: 8,”y”:[3881.1866, 3879.0869,3879.0863,3879.0869]},{“x”: 9,”y”:[3879.0869, 3880.2850,3878.0851,3880.2850]},{“x”: 10,”y”:[3880.2850, 3878.0851,3877.9851,3878.0851]},{“x”: 11,”y”:[3878.0851, 3877.9851,3877.9853,3877.9851]},{“x”: 12,”y”:[3877.9851, 3882.7873,3882.4878,3882.7873]},{“x”: 13,”y”:[3882.7873, 3883.1879,3883.0877,3883.1879]},{“x”: 14,”y”:[3883.1879, 3883.6876,3882.1863,3883.6876]},{“x”: 15,”y”:[3883.6876, 3882.2879,3882.2860,3882.2879]},{“x”: 16,”y”:[3882.2879, 3885.4881,3884.9871,3885.4881]},{“x”: 17,”y”:[3885.4881, 3886.5889,3886.1881,3886.5889]},{“x”: 18,”y”:[3886.5889, 3886.2882,3886.1886,3886.2882]}]

    dps is global
    chart is global
    —–pasted—-

    var dps;
    var chart;

    function getValuesChart() {

    var scriptUrl = “controller.php?route=graph”;
    $.ajax({
    url: scriptUrl,
    type: ‘get’,
    dataType: ‘text’,
    async: false,
    success: function(data) {
    dps = data;
    }
    });

    chart.render();
    }

    nothing is plotted.
