    Unanswered: Create sencha chart in loop


    Hi,

    I need to create gauge chart showing performance. Now the parameter can changed runtime so the number of charts.
    for that I am creating charts in loop. (just returning chart with different id and value to show)
    below is the code.
    Code:
    var data = Ext.decode(response.responseText);
    var count = data.data.length;
    for (var i=0;i<count;i++)
    {
        rec = data.data[i];
       myGaugeChart = getGaugeChart(rec.Value, rec.Name, rec.Nr);  
       GaugePanel.add(myGaugeChart);
    }
    whereas getGaugeChart function returns a gauge chart with given value.

    But the output displays only first chart. In CSS and in debugger i can see the charts are there with name given. (also in debugger values are sending properly and no error anywhere)

    I have also added label to chart(adding chart to panel and adding toolbar) , so the toolbar is displaying properly but the chart is always empty.

    Could anyone throw some light on it. how to create N chart from the basic model?

    Thanks in advance

    Ok,

    it works. I am able to create charts in loop.
    The problem with the above code is that I was doing (looping and creating charts) in Ext.Ajax.request().Success method.(in asynchronous method call)

    Now I am first retrieving all data from server side. and after that calling my method to create charts.

    Its working flawlessly
