I recently had to make some boxplots with Stata’s –graph box– command. I find this to be challenging to use since it varies from syntax from the –twoway– command set that I use all the time. I was using the –over– subcommand x2 and wanted to change the colors of each box & dots by group from the first –over– subcommand. I found some helpful details on the Statalist Forum here and here. Here’s what I did to accomplish this, using the help from the Statalist forum.
Some tweaks here: I wanted to show rotate some labels 45 degrees with –angle– and I also aggressively labeled variables and their values so I didn’t need to manually relabel the figure (which is done with the –relabel– subcommand if needed). It takes an extra 30 seconds to label variables and values, and will save you lots of headbanging fiddling with the –relabel– command, so just label your variables and values from the start.
This example uses fake data. Code follows the picture. Good luck!
