Option to drop partial buckets

[rashidkpc]

Feeding off of this: #2803

Currently we display the partial buckets, which can be confusing as it makes it appear as though the beginning and end of most time series charts are trending downward. Would be nice to have a view option to just drop the entirely. It would also have the effect of keeping the chart very stable until the next bucket has filled.

We're currently using date arrays which really do get confusing when selecting a specific data range. Dropping partial buckets would solve this, that or just limiting the charts x axis to the date range selected in the time picker.

Very much want this.

Can we get this on the roadmap? I would much rather have the ability to clip partial buckets then the way it currently is.

Using date arrays and this feature is much needed for our dashboards

When doing Serial diff aggregation, say on a counter metric that tallies up over time, the 1st bucket is always a huge positive and last a huge negative (because partial) which makes visualizing them impossible it seems.
