Dear all, I need some help with plotting boxplots in groups. I have a file of the following format: ----------------------------------------- POS DISO NODE_CAT ------------------------------------------ A 20 Hubs C 30 Nonhubs B 50 Nonhubs B 10 Hubs A 25 Nonhubs C 80 Hubs -------------------------------------------- I want to plot "boxplots" in such a way that DISO is on y-axis and the NODE_CAT is grouped according to POS. If I were to plot the above mentioned case I should get three groups of boxplots A, B, and C. Also each of the POS A, B and C should have two boxplots (one for Hubs and one for Nonhubs). Thanks in advance for any help. Anupam [[alternative HTML version deleted]]
