Expected behavior
Possibility to highlight a point in line chart. For example, I would like to highlight a clicked point by a user.

What is the motivation / use case for changing the behavior?
The click event typically produces a action that show info related to clicked point. So, It's a common requirement that a clicked point could stay highlighted.

I'd like to do this as well.
If the library doesn't support it you could perhaps do it the manual way, by finding the point element and changing the style, but exactly how, I don't know.

I understand that it creates performance issues. But it should still be a customizable option depending on the use case and defaulted to off.

Wrong issue?
