Lock tooltips by click

[AriPerkkio]

Thanks for the awesome tool!

I would like to create graphs that highlight changes between multiple dates. For this I would need to be able to show multiple tooltips at the same time.

Could the tooltips made so that they lock their visibility when their position is clicked on the graph? So something like this:

What would be the goal of having another date displayed? A specific release?

I want to highlight how many new downloads a package has got in specific timeframe, while displaying the overall graph. This would indicate the speed of growth.

Here I would have wanted to show how July 7th reached 5M and at the same time show 6M of September 8th: https://x.com/ari_perkkio/status/1836720747483414719

I am not sure this is possible
