Histogram(;100)
Description
The Histogram() function serves to evaluate and depict frequency distributions. As the default, the value range is determined by the largest and smallest value in the ChartData() function and divided into 10 bins (intervals). Please note that, as the default, two end intervals are added, i.e. when, for example, numOfBins = 3, a total of five bins are depicted. Bins are labeled by the interval limits entered in brackets. For example, [2,4) means the bin includes all values greater or equal than two and less than four.

The appearance of the bars is controlled by the arguments appearanceConstants, categoryGap and seriesGap in the Histogram() function. These arguments are discussed in detail in combination with the BarChart() function.
