问题
I'm using Highstock.JS to display a chart. But the text label on flags appear on top of the tooltip. (Picture attached).
Any idea on how to fix this?

回答1:
Probably you have set useHTML
for dataLabels for flags - disable it and will work. useHTML
create html tags, which are always above SVG elements (like tooltip background).
