Get an instance of AmChart using ID

Question

Is there any way to get an instance of the AmChart using the element Id? This is very useful when writing generic API to work with AmCharts.

<div id="myChart"></div>
<div id="myChart2"></div>
<script>
   function makeChart(id, settings) {
        var ins = AmCharts.getChart(id) ?? //need a way to find the instance
        if (ins) ins.clear();
        AmCharts.makeChart(id,settings);
   }
</script>

Answer 1

You can solve this problem like this:

function getChart(id) {
    var allCharts = AmCharts.charts;
    for (var i = 0; i < allCharts.length; i++) {
        if (id == allCharts[i].div.id) {
            return allCharts[i];
        }
    }
}

Now just call getChart("myChart") and it returns the instance.
