You can use the following methods to create one or more histograms in SAS:

**Method 1: Create One Histogram**

proc univariate data=my_data; var var1; histogram var1; run;

**Method 2: Create Panel of Histograms**

proc univariate data=my_data; class var2; var var1; histogram var1; run;

**Method 3: Overlay Histograms**

proc univariate data=my_data; class var2; var var1; histogram var1 / overlay; run;

The following examples show how to use each method with the following dataset in SAS:

/*create dataset*/ data my_data; input team $ points rebounds; datalines; A 29 8 A 23 6 A 20 6 A 21 9 A 33 14 A 35 11 A 31 10 B 21 9 B 14 5 B 15 7 B 11 10 B 12 6 B 10 8 B 15 10 ; run; /*view dataset*/ proc print data=my_data;

**Example 1: ****Create One Histogram**

**Create One Histogram**

The following code shows how to create one histogram for the **points** variable:

/*create histogram for points variable*/ proc univariate data=my_data; var points; histogram points; run;

The x-axis displays the values for the **points** variable and the y-axis displays the percentage of observations in the dataset that fall into various values.

**Example 2: ****Create Panel of Histograms**

**Create Panel of Histograms**

The following code shows how to create a panel of histograms to visualize the distribution of values for the **points** variable grouped by the **team** variable:

/*create histogram for points variable*/ proc univariate data=my_data; class team; var points; histogram points; run;

This plot allows us to quickly see that the players on team A tend to score more points than the players on team B.

Notice that the two histograms share an x-axis, which makes it easy to compare the points values between the two teams.

**Method 3: Overlay Histograms**

The following code shows how to overlay multiple histograms in one plot:

/*create histogram for points variable*/ proc univariate data=my_data; class team; var points; histogram points / overlay; run;

This type of plot is useful when you want to visualize multiple histograms in a single chart.
