@jmnn,
How could I update the crosshair?
It would be helpful for us to understand your scenario better when we look at working code live in JSFiddle than guessing the issue by looking at screenshot. I request you to create JSFiddle reproducing the issue and share it with us.
I also thought about erasing the last datapoint and adding the new one, but I did not find the instructions to erase a datapoint. Can you give some solution?
Datapoints is an array. So you can remove last dataPoint using either pop method or splice method.
