Stripplot help changing marker colours

[Pete Taylor]

Hi

I am sorry to bother you, I am trying to use stripplot to do a box and whiskers with individual data points visible. I need to code it so the markers are a different colour by the group 0 and 1. I have used separate without success, ideally on the left side I would have blue circles and on the right say red X. Is there anyway to do this

I have included the stripplot this is my code stripplot TH171base TH171v3 TH171v5 TH171v8, by(ustekinumab) box (bfcolor(gs8)) iqr jitter(1) stack h(0.5) vertical mcolor(blue)

stripplot is from SSC.

Nothing in your code asks for different colours. But when I try

sysuse auto, clear
stripplot turn trunk, by(foreign) separate(foreign)

that fails because the code is trying to stack the foreign variable twice. That may be awkward to fix, but I will have a go. I guess if I clone it first there could be a work-around.

EDIT: Fixed, so far as I can judge. Revised files will be posted on SSC in due course.

If it's urgent, please find an email for me and request copies.

Now that I think I've fixed the bug, I have suggestions on various levels. Clearly I don't have access to your data and I don't even know what it's about. But I have faked something loosely similar. Otherwise most of these small details are generic.

Use variable labels and value labels to reduce or replace cryptic or repeated text. The world doesn't need to know your variable names.

The world doesn't agree on what should be plotted outside the boxes of a box plot. Unless you explain your choice, will it be clear to readers? If you're showing all the data, do you need anything else?

The advantage of jittering is that you can shake identical points apart by adding noise. The disadvantages of jittering are that noise isn't informative as such and may even distract from people seeing structure in the data.

A fill colour inside the box makes it more difficult to see data points within it.

clear
set obs 100
set seed 2803 

foreach v in base v3 v5 v8 {
    gen TH171`v' = runiform()^3
    label var TH171`v' "`v'"
} 

gen ustekinumab = _n > 50 
label def ustekinumab 0 "toad" 1 "frog"
label val ustekinumab ustekinumab 

stripplot TH171*, by(ustekinumab, note("") legend(off)) ytitle(TH171) separate(ustekinumab) box cumul centre vertical variablelabels yla(0 "0" 1 "1" 0.2(0.2)0.8, format(%02.1f))

Thanks so much this is brilliant massively appreciated am very grateful
