boxplot trends

[paulvonhippel]

The command
-graph box y,over(x)
makes a series of separately framed boxplots for each value of a categorical variable x. But what if x is an ordered variable like year. Then what you want is a single frame around a series of boxplots that go from left to right as year increases.

Is there a command that can do that?

stripplot from SSC can do this.

[paulvonhippel]

Thank you. Which option to stripplot will do this? I'm sorry but I don't see it in the help.

[Nick Cox]

There is a bunch of examples in the help based on combining box and over() options.

If you gave a data example as we always request you'd be more likely to get code suggestions.

Returning to this I am more mystified by #1. Consider

webuse grunfeld
gen log_mvalue = log10(mvalue)
graph box log_mvalue if inrange(year, 1935, 1944), over(year) scheme(s1color)

I think you're confusing over() and by() somehow.
