sparkbar

The function plots a frequency histogram for values x and the repetition rate y of these values over the interval [min_x, max_x]. Repetitions for all x falling into the same bucket are averaged, so data should be pre-aggregated. Negative repetitions are ignored.

If no interval is specified, then the minimum x is used as the interval start, and the maximum x — as the interval end. Otherwise, values outside the interval are ignored.
