I’m using Highcharts to make this graphic:

But I need to make the border color of the tooltip to be the same as the marker color, so when I hover on the green marker the border color turns green, in the yellow marker the border color turns yellow and the same with the red marker. Do you have any idea how can I achieve this?

You have to set the
borderColortonulland then pass the pointcolorwith yourpointdata, like the following.demo
