javascript - Don't hide the tooltip when cursor is inside it in Highcharts chart -

i'm trying make tooltip stay visible when hovering inside it, move towards new series point show tooltip point instead.

i can't seem find way this, if create custom tooltip using new highcharts.tooltip() (which haven't done in example). there easy way achieve this?

here's current tooltip:

 highcharts.config.tooltip = {     enabled: true,     usehtml: true,     hidedelay: 0,     formatter: function (e) {          ... lots of html ...          return html;     } };
