On second reading: I think by "each question" you mean "every question". I doubt that you are going to make much progress with -histogram- or -twoway histogram-, assuming that is what you tried. (Again, you show no code, contrary to Statalist advice.) Look at -catplot- (SSC) or -contract- your data to frequencies and use -graph bar- or -graph hbar-.

Each variable has the answers to questions in a likert scale (always, frequently, infrequently, never, don't know). I want to plot the frequency and percent for each question side by side. Have not found a good way to do this. > * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
