What is "myid" in ZingChart docs?

353 Views Asked by froadie At 04 April 2025 at 14:23

I must be missing something simple, but...: In the ZingChart docs for the API methods, the functions all reference myid, but I can't figure out what is a ZingChart's id. For example, method getseriesvalues:

zingchart.exec('myid', 'getseriesvalues', {});

What does 'myid' refer to in this example code?

Here is my simple ZingChart example code:

 $(function(){
    var myChart = {
        type : "line",
        title : {text: "Hello ZingChart World!"},
        series : [
            {values:[5, 10, 15, 5, 10, 5]},
            {values:[2, 4, 6, 8, 10, 12]}
        ]
    };

    zingchart.render({
        id : "myChartDiv",
        height : 450,
        width : 600,
        data : myChart
    }); 
})

Now let's say I would want to invoke the getseriesvalues method on this chart - what would myid be? myChart? myChartDiv? Neither of them work...

The id property references the <div> element's id property in which the chart is injected. See the ZingChart "Getting Started" guide.

Example:

<html>
    <body>
        <script>
            var myChart = {
                type   : "line",
                title  : {text: "Hello ZingChart World!"},
                series : [
                    {values:[5, 10, 15, 5, 10, 5]},
                    {values:[2, 4, 6, 8, 10, 12]}
                ]
            };

            window.onload=function(){
                zingchart.render({
                    id : "myChartDiv",
                    height : 450,
                    width : 600,
                    data : myChart
                });
            };
        </script>

        <div id="myChartDiv"></div>
    </body>
</html>

It also used for other ZingChart methods (e.g., to subsequently bind events to your chart). For example, to get the values after initiation for this chart:

zingchart.exec("myChartDiv", "getseriesvalues", {});

You can think of id as a global variable—always referencing the same chart by name, no matter its place in the code.
