How to create a histogram chart by category using frequencies in Excel

Excel 2016
There are several ways to create a histogram chart in Excel. By the moment, Excel uses two different algorithms to calculate the data for a histogram chart:
  • For the histogram with By category option for bins, Excel calculates the data bin height as SUM of data points within the bin range,
  • For the histogram with any other option for bins, Excel calculates the data bin height as COUNT of data points within the bin range.

Thus, for web analysis or any other reporting, when it is necessary to consolidate several disparate reports with pre-calculated frequencies and bins, becomes useful a histogram chart by categories:
