Hi! If I have multiple series I see tooltip and points on lines for each one. <img width="373" alt="zrzut ekranu 2019-03-1 o 16 04 38" src="https://user-images.githubusercontent.com/1818979/53646604-eee17200-3c3b-11e9-982f-9f4cbf2ddf48.png"> If I toggle one of them, than each line is treated separately in tooltip. Is it normal? Can I change this? <img width="278" alt="zrzut ekranu 2019-03-1 o 16 05 02" src="https://user-images.githubusercontent.com/1818979/53646648-0a4c7d00-3c3c-11e9-94e3-15bfd489c2b1.png">
