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!

document.getElementById('togglebtn').onclick = () => {
var chart = document.getElementById('container').ej2_instances[0];
var series = chart.selectionModule.selectedDataIndexes;
if (series.length > 0) {
var i = series[0].series;
if (i == 0) {
chart.series[i].trendlines = [{ type: 'Linear', animation: { enable: false }, fill: 'red', width: 3, dashArray: '5,5' }];
//To maintain the selected data index
chart.selectedDataIndexes = [{ series: i }];
chart.refresh();
}
//other code here
} else {
alert("Nenhuma Série Selecionada! Por Favor selecione primeiro uma série.")
}
