I guess this example shows how to break tooltips in multiple lines.
I have the same issue with labels on category axis, can these be easily broken in multiple rows ? It would be great to be able to show html span elements there but they are encapsulated in <text> SVG elements, what can be done ?
just my 2c here, but the actual excel document is built on the client side and posted to backend just to allow the posibility to download the file ( there’s no way to create files in javascript in the browser ) . So you can check the payload that the page sends to the server to see the exact XLS buffer.
