Hi, 
I have a line chart that has a long name for the data series, so when using a shared tooltip, the tooltip exceeds the width of the screen on mobile devices (width of 270px). 
See my example here: https://jsfiddle.net/pigottm/06gh5ncy/22/
You can see how the tooltip exceeds the black-coloured area. 
How do I set a max width for the tooltip, while still using the names of each data series? 
Kind regards
Michael
