Symmetrical Jitter in Twoway Scatter

[Bradley Rose]

Dear Stata Users,

I am struggling to work out how to create non-random symmetrical jitter in my scatter plots.

I have 50 data points in each category and there is lots of overlap between the different data markers. When I use jitter it appears messy - see attached. I am aiming for something like the second attached figure - is this possible in stata and if so, which command?

Also, is there a way to include the bars for mean + 95%CI?

Many thanks!

stripplot (SSC) supports jitter, but typically displacing otherwise identical points left or right deterministically looks better.
