Assigning colors in violinplot

Signesk — Thu, 21 Nov 2019 08:21:55 GMT

Hi.

I want to assign different colors to my violinplot, but cant figure out how to. The styleatrrs is not working for me. Below my code. I want to make different colors for the plot based on value in RG (horisontal panel).

Ideally also a lighter shade in præpost_kat (vertical panel) depending on value. But that is not as important

proc sgpanel data=plot;
where rg in (0,1);
panelby rg præpost_kat / layout=lattice onepanel novarname noborder colheaderpos=bottom;
band y=tils upper=density lower=mirror / fill outline;
format rg rgx. præpost_kat bean_katx.;
colaxis display=none;
rowaxis label='TILs' grid;

run;

Its getting me this. Which I want. But I cant change the colors, and google cant help me.

thank you in advance

Are you able to post your data or a sample of it for testing?

I will have to check sine it is patient data. And do I just type it in below in colums or attach as a sasdatafile?

So I have some of the data here. It is data=sorted

But I saved it in excel and changed the name so I didnt use æ with is specifik to Denmark 🙂

and then I hade this code, before the code I posted at the first post.

proc kde data=sorted;
by rg 'præpost_kat'n;
univar tils / plots=none out=tils_dens (rename=(value=tils));
run;
data plot;
set tils_dens;
mirror=-density;
run;

Good thing you caught a fellow dane then 🙂

I made a few changes to your code and inserted an attribute map to control the colors.

Feel free to ask if you have any questions.

Thank you so much. This is exactly it!

follow up question.
I want to make the blue and red the same color and the green and gold as well

I tried changing your code like this

data myattrmap;
input ID $ value linecolor $ fillcolor $;
datalines;
myid 1 blue blue
myid 2 green green
myid 3 blue blue
myid 4 green green
;

But it remains in the four original colors.

Add the option :

attrid=myid

to the BAND statement options.

band y=tils upper=density lower=mirror / group=group fill outline attrid=myid;

Follow up question number two!

When I publish it as pdf/png or just copy it into powerpoint and enlarge it a new problem arises. The figure in the right top corner remains fine, but the three others seems to have a dotted line around them, I haven't changed anything in the code.

data myattrmap;
input ID $ value linecolor $ fillcolor $;
datalines;
myid 1 CXCD5C5C CXCD5C5C
myid 2 cx880000 cx880000
myid 3 CXCD5C5C CXCD5C5C
myid 4 cx880000 cx880000
;

proc sgpanel data=plot dattrmap=myattrmap noautolegend;
where rg in (0,1);
panelby rg prepost_kat / layout=lattice onepanel novarname noborder colheaderpos=bottom;
band y=tils upper=density lower=mirror / group=group fill outline attrid=myid;
format rg rgx. prepost_kat katx.;
colaxis display=none;
rowaxis label='TILs %' grid;
run;

I tried changing the linecolor to black and it very well illustrates the problem

data myattrmap;
input ID $ value linecolor $ fillcolor $;
datalines;
myid 1 black CXCD5C5C
myid 2 black cx880000
myid 3 CXCD5C5C CXCD5C5C
myid 4 cx880000 cx880000
;

So I want the linecolor to be solid. Thank you in advance
