I've seen the post: [Dropping first point sum aggregation visual builder](https://discuss.elastic.co/t/dropping-first-point-sum-aggregation-visual-builder/167195) and I wonder if there are any updates on being able to drop the first aggregation bucket that distorts the graph, similarly to the way you can drop the last bucket through `Panel Options --> Drop Last Bucket → Yes`.

This creates the unpleasant issue of not being able to calculate an accurate average across all the buckets.

OK, so I found a partial solution.

Instead of using a fixed time interval, I used a dynamic one.

In other words, instead of:

```auto
(30 min x 60 seconds ) / (max_metric - min_metric)

```

I did:

```auto
(max_timestamp - min_timestamp) / (max_metric - min_metric)

```

This somewhat took care of this first partial bucket that was distorting the results.

Still, the first bucket **keeps oscillating a bit** and sometimes throws an error about **division by zero**. Think it would be good to have an option to drop the first bucket similar to what exists for the last one.
