Hi all, unfortunately it was noticed in Issue 13604 [0] that when histogram is given used with a specified range and the `density=True` keyword argument out of bound values are simply discarded [1]. Discarding out of bound values makes sense when the density/normed option is not used, since in that case event counts are reported. However, when out of bound values exist, the probability density should arguably not sum up to 1 anymore. We seem to have three ways possible to continue here: 1. Call it an outright bug and fix it. 2. Add a FutureWarning, and change it later (unfortunately noisy) 3. Add a new kwarg to control what happens and a FutureWarning which can be silenced using the new kwarg. (No change will ever happen if `range` or manual bin edges were not specified.) If all agree that there is no reasonable use case for the current implementation, it would be tempting to simply change it, or use a FutureWarning (unfortunately forcing users to manually calculate the density). If there is any half-decent use case, the kwarg may be the nicer option. Personally, if no one finds has a use case, I am slightly tending towards the "bug fix" option right now. All the Best, Sebastian [0] https://github.com/numpy/numpy/issues/13604 [1] As mentioned in the documentation.
