This started a long thread involving several suggestions from Martin Weiss. The basic class of problems I take to be plotting means and confidence intervals for various cross-classified groups. I'd just like to point out that this is, not surprisingly, a problem often met before. Among various other solutions -stripplot- on SSC supports -over()- and -by()- options. Nick n.j.cox@durham.ac.uk Nikolaos Pandis I have continuous data for two trial arms (control and experiment). There are 50 measurements per arm. Data is collected at 6 time intervals. I would like to plot a bar chart with the x axis showing the intervals (0, 1, 3, 6, 9, 12 months). Within each interval I would like to have one bar for the control and one for the experimental group. The y axis shows the mean of the measurement of interest. Additionally, I would like to show the confidence intervals at each interval per treatment group. Alternatively, I would like to draw a line plot with the same y and x axis information, except that the two lines would represent the control and the experimental groups. * * 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/
