color of box plots

[Shripada Rao]

Hi, I created two box plots for the birth weight of infants based on two interventions during pregnancy (interventions 1 and 2). Both box plots have the same color. How do we make them have different colors? For example blue color for intervention 1 and red color for intervention 2. Thank you for the advice.

Thank you, very useful information

Do please read the help on graph box. The options you need (not functions) are documented. They work with Alan's method too.

. sysuse auto, clear

. separate mpg, by(foreign) veryshortlabel

Thank you Nick, it was very useful. Is there a function in the edit graph section where we could choose different colors of our choice for such graphs? Alan, when I tried your method, both graphs changed to a similar color.

You can also use the asyvars option like this:

sysuse auto
graph box mpg, over(foreign) asyvar

That said, your dataset contains 21 observations only, so you might as well as use a dotplot or strip plot to show all the details in the data.

Please don't expect people to open .dta attachments. This is explained in FAQ Advice #12. https://www.statalist.org/forums/help#stata

This code example gives a hint on one solution.

sysuse auto, clear
set scheme s1color
graph box mpg, over(foreign)
separate mpg, by(foreign) veryshortlabel
graph box mpg?
