Romain, The Histogram tries to avoid creating too many small buckets, but it is probably imposing the limits incorrectly with very small buckets. The options for the maximum number of buckets and the chartArea.width affect the computed bucket size, and there is an internal limit of 5 pixels per bucket, regardless what you specify. The range of your data is also factored in, but this includes the outliers before they are excluded.
Another misleading factor is that the ticks you see don't correspond to the bucket sizes, since it will only draw ticks that fit within the space available, so if you reduce your tick label font size, you might see more. However, given all that, it seems like it should be able to use smaller bucket sizes. The 5 pixel minimum is probably too high, and we should probably allow all the way down to 1 pixel. I am experimenting with it now, so some fixes may show up in the next release.
