Re: [Question #195651]: percentile graph
Question #195651 on Graphite changed:

Status: Open => Answered
Daniel Lawrence proposed the following answer:
One of the advantages of the graphite is its ease to build a complex
graph using multiple targets/data sources and putting them all together
on the same graph.
nPercentile(path.to.metric,99) # 99th Percentile
nPercentile(path.to.metric,97) # 97th Percentile
nPercentile(path.to.metric,95) # 95th Percentile
movingMedian(path.to.metric,5) # Median ( moving )
movingAverage(path.to.metric,5) # Average ( moving )
http://graphite:8000/render?from=-7days&until=now&width=400&height=250&target=nPercentile(path.to.metric%2C97)&target=movingMedian(path.to.metric%2C5)&target=movingAverage(path.to.metric%2C5)&target=nPercentile(path.to.metric%2C99)
Taking this approach one graph can indeed show multiple targets.

* where path.to.metric is a real - path to a metric.
