Time slider for vertical profiles

[Peter9192]

For vertical profile plots, users should be able to view the profiles at multiple time points. It would be nice to have a slider e.g. like buienradar:

If experiments/permutations have different start/end times, this could become very confusing. One solution could be to change from "time since start" to actual times in UTC. Then only experiments that have values for given time are displayed.
