I have line chart with the tooltip shared as true. The default tooltip is great. The first line is the value of the x-axis and the rest of the lines are each key name in the key color and the y value. Again perfect. All I want to do is have first line, the x-axis value, be in a html link. I realize I can use the contentFormatter, but I don’t know how to get the exact content and format of the default tooltip. I hope this makes sense. Any help appreciated. Dave
