How to create different types of histogram charts in Excel
The main differences between a histogram chart and a regular column chart are:
- a column (bar) graph describes two variables:
- the horizontal axis shows the items and
- the vertical axis shows their values,
- a histogram describes only one variable:
- the horizontal axis shows the value ranges,
- the vertical axis shows the frequencies of values within the range.
Histograms help evaluate visually where values are concentrated, what are the extreme values and the generic shape of the values distribution.
In the previous versions of Excel, to create a histogram chart it was necessary to calculate frequencies of each item (interval) and create a column or a bar chart with two parameters: items and their frequencies. Excel 2016 offers several different ways to create histogram charts:
- A simple histogram
summarizes one column or row of the numeric data, where the chart bars show the
intervals of numeric data:
- A histogram chart by categories (for non-numeric data) can be created using:
- A non-standard histogram chart is a way to create a histogram chart in other Excel versions, compare two histograms, and create a smoothed distribution plot:
