change the color of bars -BOXPLOT

[Tom Salvitti]

Hi to everybody,
I have done for the first time "Box plot by group with data point"

By default, Stata gives me graphs with the same colors. Does anyone know how to change the color of the boxes? I would need 9 different colors (one for Pups_a, one colour for Pups_b ecc)
below the syntax I wrote


twoway rbar lqt med Contesto_num, barw(.5) fcolor(gs12) lcolor(black) || ///
rbar med uqt Contesto_num, barw(.5) fcolor(gs12) lcolor(black) || ///
scatter Complex Contesto_num, graphregion(fcolor(gs15)) mcolor(black) msymbol(Oh) ///
legend(off) xlabel( 1 ".Pups_a" 2 ".Pups_b" 3 ".Pups_c" 4 ".aleF_a" 5 ".aleF_b" 6 ".aleF_c" 7 "FF_a" 8 "FF_b" 9 "FF_a" ) ///
ytitle(Complex score)


Thanks to everybody

twoway rbar lqt med Contesto_num, barw(.5)

The command defines one graph. If you want multiple plots, a legend will be necessary, otherwise differentiating bars makes no sense if there is no extra information to be conveyed. The idea is to create multiple plots where below, a loop is helpful.

webuse grunfeld, clear
keep if time<=9
twoway rbar invest mvalue time, barw(.5) scheme(s1color) saving(gr1, replace)
qui separate invest, by(time)
qui separate mvalue, by(time)
local all
forval i=1/9{
    local all "`all'  (rbar invest`i' mvalue`i' time, barw(0.5))"
}
twoway `all', scheme(s1color) saving(gr2, replace) leg(off)
gr combine gr1.gph gr2.gph, scheme(s1olor)

[Tom Salvitti]

thank you so much...
but i have to do "Box plot by group with data point" and not istograms.

[Andrew Musau]

You need to append the rest of the code if the totality is what creates the box plot. I was just focusing on the point of different colored bars (or boxes, if you wish).

[Tom Salvitti]

Thanks Andrew,
and Happy new year.

I tryed to do what you've said to me but i'm failed


I should get a graph like the picture. where is the mistake in what i wrote?

(I should use also the same colours)
I thank you infinitely

[Tom Salvitti]

i wrote this but it's not correct.

twoway rbar lqt med Contesto_num, barw(.5) scheme(s1color) saving(gr1, replace)
qui separate med, by(Contesto_num)
qui separate lqt, by(Contesto_num)
local all
forval i=1/9{
local all "`all' (rbar med`i' lqt`i' Contesto_num, barw(0.5))"
}
twoway `all', scheme(s1color) saving(gr2, replace) leg(off)
gr combine gr1.gph gr2.gph, scheme(s1olor)
scatter Complex Contesto_num
legend(off) xlabel( 1 ".Pups_a" 2 ".Pups_b" 3 ".Pups_c" 4 ".aleF_a" 5 ".aleF_b" 6 ".aleF_c" 7 "FF_a" 8 "FF_b" 9 "FF_c" ) ///

Can you post a sample of your data using dataex?

There are variables missing in #8 from your code in #1. Do you generate these subsequently? If so, also enclose the code. Otherwise, ensure that the following variables are present.
