A histogram or Pareto (sorted histogram) is a column chart that shows frequency data. Here’s a typical example:
To create a histogram in Excel, you provide two types of data — the data that you want to analyze, and the bin numbers that represent the intervals by which you want to measure the frequency.
Create a histogram chart

Select your data.
(Shown here is the data that was used to create the sample histogram shown above.)

Click Insert > Insert Statistic Chart > Histogram.
You can also create a histogram from the All Charts tab in Recommended Charts.
Tips:

Use the Design and Format tabs to customize the look of your chart.

If you don't see these tabs, click anywhere in the histogram to add the Chart Tools to the ribbon.
Configure histogram bins

Rightclick the horizontal axis of the chart, click Format Axis, and then click Axis Options.

Use the information in the following table to decide which options you want to set in the Format Axis task pane.
Option
Description
By Category
Choose this option when the categories (horizontal axis) are textbased instead of numerical. The histogram will group the same categories and sum the values in the value axis.
Tip: To count the number of appearances for text strings, add a column and fill it with the value “1”, then plot the histogram and set the bins to By Category.
Automatic
This is the default setting for histograms. The bin width is calculated using Scott’s normal reference rule.
Bin width
Enter a positive decimal number for the number of data points in each range.
Number of bins
Enter the number of bins for the histogram (including the overflow and underflow bins).
Overflow bin
Select this check box to create a bin for all values above the value in the box to the right. To change the value, enter a different decimal number in the box.
Underflow bin
Select this check box to create a bin for all values below or equal to the value in the box to the right. To change the value, enter a different decimal number in the box.

Formulas used to create histograms in Excel 2016
Automatic option (Scott’s normal reference rule)
Scott’s normal reference rule tries to minimize the bias in variance of the histogram compared with the data set, while assuming normally distributed data.
Overflow bin option
Underflow bin option
