How can I show one tooltip for multiple series?

Let's say I have line chart with 3 different series.

I am using getItemForPoint() function to get the nearest node on each line.

Now, when I move my cursor over the graph, all three closest nodes to my cursor on 3 graphs get highlighted and since tips are implemented for each series. I will see 3 overlapping tips simultaneously.

Is there a clean way of showing just one tooltip that has all 3 graphs info in it?
