You can use a procedure such as PROC MEANS to calculate the means and standard errors. You can then use these values to calculate the upper and lower error bar limits in a DATA step. Use the HILOCTJ interpolation with PROC GPLOT to generate the graph. These sample files and code examples http://support.sas.com/kb/42515 are provided by SAS Institute Inc.

This sample illustrates how to plot means with standard error bars from calculated data with the GPLOT procedure. The graphics output on the Results tab was produced using SAS 9.2. Submitting the sample code with releases of SAS prior to SAS 9.2 might produce different results. /* Set the graphics environment */ goptions reset=all cback=white border htext=10pt htitle=12pt; /* Create sample data */ data test(drop=i); do i=1 to 10; do xvar=1 to 5; yvar=ranuni(0)*100; output; end; end; run; proc sort data=test; by xvar; run; /* Calculate the mean and standard error for each X */ proc means data=test noprint; by xvar; var yvar; output out=meansout mean=mean stderr=stderr; run; /* Reshape the data to contain three Y values for */ /* each X for use with
bars that represent ± 1 standard deviations. To do this, we tick the Dispay error bars checkbox and then, under the -Error Bars Represent- https://statistics.laerd.com/spss-tutorials/bar-chart-using-spss-statistics-2.php area, we check the Standard deviation radio box, and in the Multiplier:, enter "1".

Note: If you are creating your bar chart as part of carrying out inferential statistical tests (e.g., independent-samples t-test, paired-samples t-test, one-way ANOVA or repeated measures ANOVA), rather than just descriptive statistics, you may also want to include "confidence intervals". We explain why and show error bars you how to do this in our enhanced content. Click the button. You will be presented with the following screen (showing the error bars added in the "Chart Preview Area"): Published with written permission from SPSS Statistics, IBM Corporation. We do not need to do anything in the following screen in this example. However, it does present some options which you might find useful. You can use the and error bars in to rearrange the order of the categories and the button to exclude a category. If you make a mistake and exclude a variable you later want to include, you can simply click the button in the Excluded: box. Published with written permission from SPSS Statistics, IBM Corporation.
