As it turns out, `makeBuckets` always returns at least the +Inf bucket. So a native histogram will never be rendered. The canonical way of marking a native histogram, even one without any observations yet, is to have at least one span. With this commit, a native histogram is rendered if there is at least one span. Otherwise, a classic histogram is rendered. Signed-off-by: beorn7 <[email protected]>

In PGW, we are rendering both types of buckets in case both exist, so that should be fine. |

makeBucketsalways returns at least the +Infbucket. So a native histogram will never be rendered. The canonical
way of marking a native histogram, even one without any observations
yet, is to have at least one span.
With this commit, a native histogram is rendered if there is at least
one span. Otherwise, a classic histogram is rendered.
I have also made the documentation a bit more explicit about this and re-added a classic histogram example.
