Histogram rarely contains information that is relevant for end users, so we haven’t created a GUI for this feature, but you can get it by a few lines of Python code. See a complete example (including generating sample data, computing the histogram, and plotting the result) in the [script repository](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#get-histogram-of-a-segmented-region).
