How can I change the violin colors in vioplots?

[Mohannad Awad]

I am trying to change the violin colors in a violet command, I tried adding bar(3, fcolor(bluish gray)), box(3, fcolor(bluish gray)) violin(3, fcolor(bluish gray) to my command, but nothing seems to work

Welcome to Statalist. For user-written commands, you are requested to make this explicit when making reference to them in your description and as a matter of courtesy also acknowledge the authors. The relevant command here is vioplot which is a modification of the box plot and the authors are Nick Winter and Austin Nichols. The help file will show you that the graph contains 4 components: density, bar, line, and median. You can specify colors as follows:

*TO INSTALL TYPE ssc install vioplot
sysuse auto
vioplot mpg, over(rep78) bar(color(black)) density(color(ebg)) line(color(midblue)) median(color(red))

thank you for this. What if you have two variables though?

bar(1, color(black))

does not work, for example

vioplot doesn't appear to support varying colours.
