Here’s my solution: https://jsfiddle.net/e6td4sh0/
I use the new floating-bar-feature from the quite new chart.js
2.9-version.
Everything works, except the timezone and the time format for the tooltip. I post the complete code here when I solved these problems. If somebody else solves them I would be glad if he/she updates my answer with the correct code.
