Add trendline of selected series chart

Hi,

How can I add a trendline by selecting a series and clicking a button?

The code I want is something like this:


function AdicionarTendencia(ch) {
    var chart = document.getElementById(ch).ej2_instances[0];
 
    var series = chart.selectionModule.selectedDataIndexes;
 
    if (series.length > 0) {
 
        var i = series[0].series;
 
        chart.series[i].trendlines.add();

    }
    else {
        alert("Nenhuma Série Selecionada! Por Favor selecione primeiro uma série.")
    }
}

Is there a way to do this?

Thank you!
