问题
I need to show highchart markers only on hover state and in the legend at all times. I don't want it to show on normal state in the chart. I searched for this and found this post which did not work for me
Series markers disable on lines and enable on legend in Highchart
回答1:
You can reset drawPoints function.
Highcharts.Series.prototype.drawPoints = function() { };
