I’m using this chart on my page:
// Themes begin
am4core.useTheme(am4themes_animated);
// Themes end
// Create chart instance
var chart = am4core.create("chartdiv", am4charts.XYChart);
// Add data
chart.data = [{

<div id="chartdiv"></div>But it only has one data line. I would like to add another, in red color, as I do?
OBS: THE AmCharts has another template with two or more lines, but it has no zoom.
