Get the point coordinates in custom tooltip function

[julienfouilhe]

When we use the custom tooltip function, we get x and y coordinates calculated given the the height and the width of the built-in tooltip system. Would it be possible to get the points x/y coordinates in the graph in order to be able to display easily a really custom tooltip?

For instance, I want mine to display always at the top of the point. Having coordinates calculated for the tooltip to be on the left is annoying and makes it pretty much impossible to calc the point position.

Thanks

I don't think this is too hard to add. I'd be happy to look at a PR for it.

👍 Yes, it would be really great to have such an option, because its a pain to position custom tooltips :)

Relative is better. I think that's what you are asking. You also have to consider where the chart is, to populate the tool tip at one point. I always try to get tooltips to be relative to the viewport. If you restrict it to show up at the top, you may run into issues when that chart is aligned to the top of the viewport. Then relative to eachother, so they don't bump into eachother, when mousing over data that is side-by-side. Lots of math. :)
