Yes, histograms can be extremely useful. The SmartShare applications use histograms for a variety of purposes, e.g. function profiling (like yours), number of packets per RX burst, number of packets per flow, and much more. The distribution index can be linear (like yours), log2, or - for higher resolution - floating point with 3 or 4 bits mantissa and 5 or more bits exponent. Please provide generic histograms as a proper library, not tied to a specific driver, and not specifically using "time" as parameter.
