Deleting labels in Prometheus

Question

I'm using Prometheus to do some monitoring but I can't seem to find a way to delete labels I no longer want. I tried using the DELETE /api/v1/series endpoint but it doesn't remove it from the dropdown list on the main Prometheus Graph page. Is there a way to remove them from the dropdown without restarting from scratch?

Thanks

This happens to me also, try to include the metric name when querying for labels' values like this:

    label_values(node_load1, instance)

If you delete every relevant timeseries then it should no longer be returned. If this is not the case, please file a bug.
