Creating bar charts in SAS is a simple process that involves using the proc sgplot procedure and the bar statement to plot data. You can also use the vbar statement to plot vertical bars and hbar statement for horizontal bars. To further customize your bar chart, you can also add additional options such as color, legend, and labels. Examples of how to create bar charts in SAS are provided in the following code blocks.
You can use the following methods to create different types of bar charts in SAS:
Method 1: Create One Bar Chart
proc sgplot data = my_data;
vbar variable1;
run;
Method 2: Create Stacked Bar Chart
proc sgplot data = my_data;
vbar variable1 / group = variable2;
run;
Method 3: Create Clustered Bar Chart
proc sgplot data = my_data;
vbar variable1 / group = variable2 groupdisplay = cluster;
run;
The following examples show how to use each method with the following dataset in SAS:
/*create dataset*/ data my_data; input team $ position $ points; datalines; A Guard 8 A Guard 6 A Guard 6 A Forward 9 A Forward 14 A Forward 11 B Guard 10 B Guard 9 B Guard 5 B Forward 7 C Guard 10 C Forward 6 C Forward 8 ; run; /*view dataset*/ proc print data=my_data;
Example 1: Create One Bar Chart
The following code shows how to create a bar chart to visualize the frequency of teams:
/*create bar chart to visualize frequency of teams*/
title "Bar Chart of Team Frequency";
proc sgplot data = my_data;
vbar team;
run;
If you’d like a horizontal bar chart instead, simply use the hbar option:
/*create horizontal bar chart to visualize frequency of teams*/
title "Bar Chart of Team Frequency";
proc sgplot data = my_data;
hbar team;
run;
Example 2: Create Stacked Bar Chart
The following code shows how to create a stacked bar chart to visualize the frequency of both team and position:
/*create stacked bar chart*/
title "Stacked Bar Chart of Team & Position";
proc sgplot data = my_data;
vbar team / group = position;
run;
This chart allows us to visualize the frequency of each team along with the frequency of positions within each team.
Example 3: Create Clustered Bar Chart
The following code shows how to create a clustered bar chart to visualize the frequency of both team and position:
/*create clustered bar chart*/
title "Clustered Bar Chart of Team & Position";
proc sgplot data = my_data;
vbar team / group = position groupdisplay = cluster;
run;
This bar chart displays the same information as the previous bar chart, except the bars are “clustered” together instead of stacked on top of each other.
