Hi,

I want to format tooltip datetime at xAxis and I added "xDateFormat" config to tooltip option already but it is not working.

Thanks

Hi huy21110027781,

Thanks for contacting us with your question.

xDateFormat property is not applied in this case, because you overwrite the tooltip value in the formatter callback. Using xDateFormat value in formatter should help in this case:

Let me know if it was what you were looking for.
