Suggest a feature: Option to click on the data point

I would like to be able to click on a data point and the details just pops up similar to the hovering except the pop-up just stays on the screen until you close it. Sometimes hovering alone isn't enough. If this happens, it will be nice to be able to move that pop-up box.

If we already have that feature, I apologize, iono how to use it. But if we don't, it would be nice to add it.
