I’m so dumb, I figured it out. To do this, just set the visibility to false for the line you want hidden, like this:
visible: false,
Then, setup a click event handler so you can turn the line ‘on’ when it’s clicked in the legend.
legend: {
cursor: "pointer",
itemclick: function (e) {
//console.log("legend click: " + e.dataPointIndex);
//console.log(e);
if (typeof (e.dataSeries.visible) === "undefined" || e.dataSeries.visible) {
e.dataSeries.visible = false;
} else {
e.dataSeries.visible = true;
}
e.chart.render();
}
