For example, if we choose the ‘foreign’ variable, which is a binary variable, Stata will generate two graphs one for observations where the variable equals 1 (Foreign), one for those where it equals 0 (Domestic). We can then choose our desired variable from the drop down menu below. This is done by going to the ‘By’ tab and checking the option labelled ‘Draw subgraphs for unique values of variables’. Graphs for different subcategories of a variable can also be created. Generating Histograms For Categorical Variables To add a density plot to your histogram, go to the ‘Density plots’ tab in the dialogue box and check ‘Add normal-density plot’ and/or ‘Add kernel density plot’. The legend for a graph can be displayed by checking the ‘Show legend’ radio button under the ‘Legend’ tab. The new graph will be opened in a new tab in the graph window. Naming graphs allows you to generate and compare multiple graphs at once. Under the ‘Overall’ tab, you can specify the name of the graph in the input field under ‘Name of graph’. When a new graph is created, it replaces the previous one and is also named ‘Graph’. Naming The Graphīy default, Stata names any graph generated as ‘Graph’. The layout of the histogram generated will now match the Stata Journal default. We can, for example, use a template called ‘Stata Journal’ and press Submit. We can alter the layout and color scheme of the histogram in Stata from the drop-down menu called ‘Scheme’ in the ‘Overall’ tab.

Tips and Tricks Histogram Scheme Instead of clicking ‘Ok’ which closes the dialogue box, we click ‘Submit’ which generates a histogram but keeps the dialogue box open so we can make any further changes conveniently. The input field under ‘Notes’ can be utilized to add any notes (such as the source of data) under the graph.

Under the ‘Titles’ tab, we can key in our desired heading for the histogram in the input field under ‘Title’. The number of bins therefore needs to be chosen appropriately. If we have too many bars, we are not summarizing the data enough, whereas if the number of bars is too low, we are summarizing too much. We only change the width of the bin to ‘3’ by first checking the checkbox beside the respective field and entering in the value. Decreasing the number of bins will increase the width of each bin. In the ‘Bins’ section, users can type in the number of bins, width of the bins and the starting value/lower limit of the first bin. You can also specify whether your variable is discrete or continuous by choosing any one of the options under the ‘Data’ section. Therefore, you can choose only one option for the Y-axis. Radio buttons indicate that the options provided are mutually exclusive. Open the dialogue box again and under the ‘Y axis’ section, check the radio button titled ‘Frequency’. Secondly, we want the vertical axis to display the frequency instead of density which it shows by default. Firstly, we want to adjust the bar width. In our example, the histogram for the variable ‘mpg’ has eight bins that start from the x-axis value of 12. In the results section, you will notice the number of bins, their starting value and the bin width also reported. Therefore, the drop-down menu in the dialogue box allows you to choose just one variable for the histogram. It should be noted that a histogram can show the frequency distribution (or density, frequency or fraction) of only one variable at a time. A separate window with the histogram displayed will be opened. In the dialogue box that opens, choose a variable from the drop-down menu in the ‘Data’ section, and press ‘Ok’. To create histogram in Stata, click on the ‘Graphics’ option in the menu bar and choose ‘Histogram’ from the dropdown. We now want to create a histogram for the variable ‘mpg’ which holds data for the mileage of an automobile. Click on the ‘use’ option in front of the dataset name in the list in order to load it in memory. Go to File -> Example Datasets -> “Example Datasets Installed With Stata”. Let’s load one of Stata’s inbuilt datasets to see how histograms are created. In this article we are going to learn how to create Histogram in Stata

Histograms are a common way of graphically representing the frequency distribution of data.
