A histogram is a type of chart that uses rectangular bars to represent frequencies. It’s a helpful way to visualize the distribution of data values.
- Bin width: Select this option to specify how big the range of each bin should be. For instance, if you were to set the bin width to 12, each bin would represent a range of 12 numbers. Excel would then plot as many 12-number bins as it needs to account for all the values in your source data.
- The bin width specifies how big the bin needs to be. Modifying the Bin Width. This will make the frequency of ages in a group increased by 2 at each iteration. Histogram with a Bin Width of 2. We can also change the number of bins of a histogram in excel. To make the histogram have 5 bins, we need to go to step 2 and set the.
- I have no idea why the horizontal bins can't show a single number to represent a size of one or why I can't get rid of the superfluous vertical grids. The horizontal axis settings are: Bin width 1.0 why the decimal place?, Number of bins 56, Overflow bin 76.0, Underflow bin -13.0, Number category General, Format code General.
Enter your bin number interval. Type into the 'Bin width' text box the value of an individual bin number, then press ↵ Enter. Excel will automatically format the histogram to display the appropriate number of columns based on your bin number. For example, if you decided to use bins that increase by 10, you would type in 10 here.
This tutorial explains how to create and modify histograms in Stata.
How to Create Histograms in Stata
We’ll use a dataset called auto to illustrate how to create and modify histograms in Stata.
First, load the data by typing the following into the Command box:
use http://www.stata-press.com/data/r13/auto
We can get a quick look at the dataset by typing the following into the Command box:
summarize
We can see that there are 12 total variables in the dataset.

Basic Histogram
We can create a histogram for the variable length by using the hist command:
hist length
Histogram with Frequencies
By default, Stata displays the density on the y-axis. You can change the y-axis to display the actual frequencies by using the freq command:
hist length, freq
Histogram with Percentages
You can also change the y-axis to display percentages instead of frequencies by using the percent command:
hist length, percent
Changing the Number of Bins
When you use the hist function in Stata, it automatically tells you how many “bins” it used. For example, in the previous examples it always used 8 bins:
However, we can specify the exact number of bins by using the bin() command. For example, the following code tells Stata to use 16 bins instead of 8:
hist length, percent bin(16)
We can also tell Stata to use fewer bins:
hist length, percent bin(4)
Notice that the more bins you use, the more granularity you can see in the data.
Adding a Normal Density to a Histogram
You can add a normal density curve to a histogram by using the normal command:
hist length, normal
How to Modify Histograms in Stata
We can use several different commands to modify the appearance of the histograms.
Adding a Title
We can add a title to the plot using the title() command:
hist length, title(“Distribution of Length”)
Adding a Subtitle
We can also add a subtitle underneath the title using the subtitle() command:
hist length, title(“Distribution of Length”) subtitle(“n = 74 cars”)
Adding a Comment

We can also add a note or comment at the bottom of the graph by using the note() command:
