Description
We have a 15s resolution on the whisper data and the metric is sent to graphite once every 15s. This causes the most current "bucket" to sometimes return null until it has received the update. I can send metrics more frequently, but there will always be a window in which the current bucket" has not yet received a metric and will return null.
When Grafana requests metric data during that window, the "Current" value in "Legend Values" is null.
Is it possible to either a) if current is null, return the previous value (if previous value is null, then set current to null, appropriate for missing 2 metric buckets), or b) define a window in which the current value should be taken (e.g. the most current value within a 30s window - given that we're updating once every 15s -- or most current value within 2m if we're updating every 1m).
Thanks so much for the wonderful project!
