NEED HELP!!! Spider Plots w/ Proc Template

HitmonTran — Sun, 23 Oct 2016 18:25:00 GMT

Hi, I am having trouble using an existing Swimmer Plot program and changing it into a Spider Plot.

I'm not familiar with graphs and having trouble changing the y-axis from "one record per subject" to "% change in lesion size from baseline"

Here is the original Swimmer's plot code below:

(I believe I have to change YVAR=_n_. where "_n_" is the sequence # of each subject. And it's one subject per record).

I created a variable lespct1-lespct6, which is the "lesion percentage change from baseline".

If I can somehow use that variable instead of "_n_" then I think the graphs should change, no?

Thanks in advance!

data final;
set sw;
YVAR = _n_;

   if ongoing= 1 then do;
      xongo= xtime + 0.25;
   end;
* if conrflag = 'Y' then
*     xconrsp= -0.5 ;
* else xconrsp= . ;

format dstage stage. ;
run;

data _null_;
   set final end=last;
   if last then do;
      call symput('viewmax', left(put(_n_,3.)));
      call symput('thickn', left(put(int(250/_n_),3.)));
   end;
run;

proc print data=final;run;

What is a "Spider Plot" supposed to look like? Google shows some Radar Plots. Is that what you want? Please share some example images, and you full code with data so we can run the program and see what is happening. Also, what Version of SAS are you using?

The happy faces in the code is suppose to be a ": )"

just running your data steps, fixed some typos. However, macro variable &crdte is not found in:

xtime = round((min("&crdte"d, datepart(eosdat), datepart(eotdat)) - ex1dt)/7,0.1);

&crdte can be replaced with today's date : '21OCT2016'd. thanks!

xtime = round((min('21OCT2016'd, datepart(eosdat), datepart(eotdat)) - ex1dt)/7,0.1);

Your data appears quite complicated. Here is a simple example on how to create such a Spider plot.

so it looks like I I need to manipulate my data from one record per subject to multiple records per subject with one variable for "% change from baseline"?

You want to display the tumor size change from baseline for each subject over time. This is called a SERIES plot, and needs multiple observations with (x,y) data, that are connected by line segments. When you have multiple series in the data, you need a curve id (Group) which can be the Subject column. Now, since you want to color each line by the response group classification (Complete Response, etc), you need to provide that classification as a separate option called GroupLC. This idea is also sometimes also referred to as a "Speghetti Plot",

Is there a way to change the color of the swimmer lanes?

And is there a way to add a second title to the legend outside the graphs?
