When using Clustering in the Map Viewer, it defaults to displaying a count of features. Since counts are inherently integers, the legend should also be limited to integer values.
If the range of the values being clustered contains fewer than 5 distinct integers, then it should reduce the number of legend items to maintain each being an integer.
If the range needs breaks, then those breaks should also be integers; adjusting the number of items in the legend to accommodate the range.
For example, if you happen be viewing an extent where the count of features ranges from 2 to 3, then the legend should only have two values in it: 2 and 3. It should not display fractional values, as it currently does:
It is confusing to indicate fractional counts, as it is impossible to have a fractional count. Furthermore, there are no symbols on the map that are not 2 or 3, so it overly complicates the legend to have those fractional values presented.
