Plot multiple y measures with one x measure

Abishekaa — Fri, 22 Apr 2022 04:04:26 GMT

This is a sample of my data - Basically, I have multiple measures for each patient, and a calculated mean of those measures. How do I create a scatterplot of the measured values (y) vs the mean value (x) of each patient in one graph? It seems pretty simple, but I have used sgplot and gplot and am stumped!

ID m1 m2 m3 m4 mean

1 5 6 2 1 4

2 2 1 1 0 1

3 9 . 8 7 8

4 2 . . 2 2

This is the type of plot I would like to create:

It really helps when you claim something doesn't work if you 1) show the code you tried and 2) describe why it didn't meet your needs.

Sgplot, one way

proc sgplot data=have noautolegend;
   scatter y=m1 x=mean/markerattrs=(symbol=circlefilled color=blue);
   scatter y=m2 x=mean/markerattrs=(symbol=circlefilled color=blue);
   scatter y=m3 x=mean/markerattrs=(symbol=circlefilled color=blue);
   scatter y=m4 x=mean/markerattrs=(symbol=circlefilled color=blue);
   xaxis label='Horizontal Label';
   yaxis label='Vertical Label';
run;

If you do not specify a symbol then each individual scatter will use a different symbol by default (until it runs out of default settings anyway) and if you don't specify a color each plot will have a different color. Without the Noautolegend to suppress the legend each of the marker symbol/colors would have legend entry.

Or possibly (which is likely more flexible in term of multiple measures)

data have;
   input ID m1 m2 m3 m4 mean;
datalines;
1   5     6    2    1     4
2   2     1    1   0      1
3   9     .    8    7      8
4   2     .    .     2      2 
;

proc transpose data=have out=trans;
   by id mean;
   var m1-m4;
run;

proc sgplot data=trans;
   scatter x=mean y=col1/group=_name_;
   label _name_='Measure';
   xaxis label='Horizontal Label';
   yaxis label='Vertical Label';

run;
