Functions

func PromResultToPromSeriesSet

func PromResultToPromSeriesSet(res *promql.Result) (plot.SeriesSet, error)

PromResultToPromSeriesSet copies res and converts it to a format suitable for use with the terminal plotting library. It copies since query results are generally not usable beyond the lifetime of the query.
