I am trying to move the tick labels down but I couldn't find in the documentation on how to do that. I've tried using the tick label prefix, by means of adding spaces there, but that seems to come back into the hover info. Is there a way to do this?
There's no easy way to do this at the moment, unfortunately.
Using tickprefix or ticksufix is an ok hack, but you can also try using ticks: 'outside' with tickcolor: 'rgba(0,0,0,0)'
