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.
This tutorial explains how to create and modify histograms in Stata.
Automatic – Excel does the heavy lifting for you, and determines what the size of each bin would be. Bin width – You tell Excel how many units each bin should be. In our example below, we are telling Excel that we want each bin to cover 9,984 units each. Make a Histogram in Microsoft Excel 2016 for Mac A histogram displays the frequency values in a proportional graph. You're going to need some data to work with. Here's the data used in the example below. Type this into a blank worksheet: Follow these steps to make a really great looking histogram. Re: How to change bin number/width in a histogram in Excel for Mac (Office 2020) Found the answer: Select your histogram chart by clicking on one of the bins. The options to modify the bins will be available under the histogram tab in the Format Data Series panel on. I need help with a histogram chart on excel 2013 and the bin width setting. In 18 mins I need to change the bin number for my histogram on excel online. Formatting a Histogram Chart Once you’ve inserted a histogram into your Microsoft Excel worksheet, you can make changes to it by right-clicking your chart axis labels and pressing the “Format Axis” option. Excel will attempt to determine the bins (groupings) to use for your chart, but you might need to change this yourself.
How to Create Histograms in Stata
We’ll use a dataset called auto to illustrate how to create and modify histograms in Stata.
How To Modify Bin Width For A Histogram In Excel Mac Download
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:
hist length, note(“Source: 1978 Automobile Data”)
Follow the following should answer. This is a new help sheet so anyproblems email pern_di...@yahoo.co.uk.
Change the 0 to N with required number. Column B would contain your
data.
Histograms
Have the data in column B. To do a random dataset in cell B1 type
=randbetween(1,100) and enter. Drag the formula to B100 so that when
entered a number appears in each cell. Click CTRL HOME.
In cells D4 have the label Lower Limit and in E4 Upper Limit.
Assuming that the data is between 0 and 100 have entries in Lower
Limit for 0, 10, 20, 30, 40, 50, 60, 70, 90. Under Upper Limit have
10, 20, 30, 40, 50, 60, 70, 90, 100. Change these numbers to suit your
dataset.
Have the following labels in G4 Category, H4 Score, and I4 Score 2.
Under the Category culomn in G5 enter 0 to 10, G6 10 to 20, G7 20 to
30, G8 30 to 40, G9 40 to 50, G10 50 to 60, G11 60 to 70, G12 70 to
80, G13 80 to 90, G14 90 to 100.
In cell H5 enter this formula:
=COUNTIFS($B$1:$B$1000,'>='&D5,$B$1:$B$1000,'<='&E5)
An alternate formula for 2003 and earlier is:
=SUMPRODUCT(--($B$1:$B$1000>=D5),--($B$1:$B$1000<=E5))
In cell I5 use =H5 as this is going to be used to give a trendline.
Now the basics and done do the following to format and make the
histogram:
Type Category Histogram in G2.
Click on Cell G4

If on a chart sheet right click and Move to a normal sheet.
If pie chart is made right click and select Change Chart Type, Bar

Click on the Vertical Axix and change the minimum to 80.
Click on the first blue column.
Change the Gap Width to 0%.
With the dialog box open click on a blue bar twice. The dialog box
should have change to Format Data Point.
Click on Fill and change colour.
Click on the next blue column and repeat.
Click on the Line and the dialog box should change to Format Data

Select Line Style and change the Width to 5 pt. Click on Close.
If you do not want the gridlines click on one and press Delete.
Click on the Legends and Delete.
In Excel 2003 and earlier right click and fill in the Wizard.
In 2007 do the following: Go to the Layout Tab, Axes, Axes, Primary
Horizontal Title, Show Left to Right Axix.
Click on the Axix title that appeared and in the formula bar click and
then click on H4 and enter.
Go to the Layout Tab, Axes, Axes, Primary Vertical Title, Show Default
Axix.
Click on the Axix title that appeared, click on the formula bar, and
click on G4 and enter.
Click on Layout tab, Chart Title, Above Chart.
Click on the Chart Title that appeared and click on cell G2.
By using a formula to display the title if they are changed the chart
will automtically update.
When the chart is selected you can resize the chart by dragging on a
corner and pressing the left button. Move the chart around the sheet
when a four arrow appear under the mouse curor. To move to a new
chartsheet right click, Move Chart, and follow dialog.
