SAS Graph with Error Bars
Example SAS Code
The following code produces the graph above -- which displays means as bars and includes 95% error bars. The data set used for this example is found here and the SAS code is here. Save the date file to the following location: C:\SASDATA\SOMEDATA.SAS7BDAT or change the code to point to the location where you have saved the data file.
Note:
- The Pattern option is used to make the bars gray
- The INSIDE=MEAN causes the mean values to be displayed within the bars
- The CLM=95 specifies the 95% CI
- The ERRORBAR=TOP causes the error bars to be displayed on the top of the bars
