Hi,

I have a dataset that looks something like this

data have;
infile datalines;
input patid $4. therapycode1 $10. visit1 duration_to_next_treatment1
therapycode2 $9. visit2 duration_to_next_treatment2 
therapycode3 $9. visit3 duration_to_next_treatment3;
datalines;
A1 FL+MM    1 100 LL+NM    2 70 FL+MM    3 40
A2 LL+MN    1 80  CC+WW    2 20 CC       3 60
A3 ZZ+BB+NN 1 50  ZZ+QQ+NN 2 66
A4 ZW+BR+MM 1 11  BR+HH    2 40 YY       3 44
A5 ZZ+BB+NN 1 0   CC       2 55
A6 ZZ+BK+NN 1 200 ZZ+BK*NN 2 6  ZZ+AA*SS 3 20
A7 QQ+HH    1 30  GG       2 89          3 15 
A8 XX+CC    1 15 PP+DD+HH  2 11 
A9 HH       1 70 ZZ+UU     2 33 DD+UU    3
A10 LL      1 300 TT+GG+RR 2 20 XX+BB    3 88
.               .
.               .
.               .
.               .
.               .

A90          1 88     
;
run;

The dataset has about 90 patients, the variables goes from about therapycode1, visit1, duration_to_next_treatment1 --therapycode9, visit9, duration_to_next_treatment9

I would like to represent this with a swimmer plot, I really don't know how to go about this, I have been racking my brain all day. Maybe someone can help.

I will really appreciate that

I don't understand this. What do you want to represent exactly?

[Anita_n]

I wish to represent for each patient the time it took from the first treatment (which is the variable duration_to_next_treatment1 calculated in days) during the first visit(visit1)to start the next treatment in visit2 and from the second visit to the third visit (duration_to_next_treatment2) etc. Sorry I hope you can understand me better now.
