NEED HELP! swimmer plots - change swim lane colors PROC TEMPLATE

[HitmonTran]

does anyone know if there's a way to change the swimmer lane colors in PROC TEMPLATE swimmer plots??

also if you can add a second title in a legend? thanks

I'm just guessing:

You may find relevant information in:

     http://www.pharmasug.org/proceedings/2014/DG/PharmaSUG-2014-DG07.pdf

a line taken from this link:

     scatter X=crstart1 Y=subjn /markerattrs=(symbol=trianglefilled size=9 color=red);

Your posts of the same question under different headings is a bit confusing.  Also, it would be easier to help if you add more information, such as an image of what you want.  Having said that, you can find some information in this blog article.  If you want to change the colors of the "Disease Stage" bars, then you can use a STYLEATTRS statement to set your colors, or use a Discrete Attributes Map (DATTRMAP).  

You can find more information on these options in the same blog by searching for those terms, or searching on Google or in SAS documentation.

Hi Sanjay,

I'm using Proc Template. Below is the code.  Under "vectorplot" statement, I want to assign specific colors to "group=DSTAGE" (bold font). "DSTAGE" are different cohorts to the study. Attached is an image of my current plot.  The colors are hard to distinguish from each other.

how do I apply the proc sgplot code onto this? thank you.

Proc TEMPLATE;
   define STATGRAPH GTL_GRAPH;
   BEGINGRAPH /BORDER=False;

   LAYOUT OVERLAY /
   YAXISOPTS= (DISPLAY=(LABEL) OFFSETMIN=0.1 OFFSETMAX=0.2 LABEL="Patients"
   LABELATTRS=(FAMILY="Arial" WEIGHT=bold SIZE=11pt)
   LINEAROPTS=(VIEWMIN=1 viewmax=%eval(&viewmax - 3) TICKVALUESEQUENCE=(start=1 end=&viewmax INCREMENT=1)))
   XAXISOPTS=(OFFSETMIN=0.05 OFFSETMAX=0.05 LABEL="Drug Treatment (weeks)"
   LABELATTRS=(FAMILY="Arial" weight=bold size=11pt) TICKVALUEATTRS=(COLOR=BLACK)
   LINEAROPTS=(VIEWMIN=0 VIEWMAX=&maxweek TICKVALUESEQUENCE=(START=0 END=&maxweek INCREMENT=&weekint)));
 *  ENTRY HALIGN=center TEXTATTRS=(FAMILY="Arial" COLOR=black SIZE=11pt WEIGHT=bold) "Dose Cohort: Drug 20mg/d (N=10)"/valign=top ;

* draw swimmer lane bars;
 
   VECTORPLOT X=XTIME Y=YVAR XORIGIN=0 YORIGIN=yvar/GROUP=DSTAGE
   DATATRANSPARENCY=0.4 ARROWHEADS=FALSE LINEATTRS=(PATTERN=1 THICKNESS=6));

   SCATTERPLOT X=eval(XTIME+999) Y=YVAR/GROUP=DSTAGE  Name="TYP" DATATRANSPARENCY=0.3 MARKERATTRS=(SYMBOL=squarefilled SIZE=9) ;


 * draw SUBJECT on the bar;
   SCATTERPLOT X=eval(XTIME-XTIME) Y=eval(YVAR+0.6)/GROUP=DSTAGE DATALABEL=SUBJECT DATALABELATTRS=(COLOR=black SIZE=5pt) MARKERATTRS=(size=0) ;

You will find full documentation on VECTORPLOT  in:

  http://support.sas.com/documentation/cdl/en/grstatgraph/67882/HTML/default/viewer.htm#n0kbxb6xovwq2b...

see next options in the linked page: 

COLORMODEL=color-ramp-style-element | (color-list)

COLORRESPONSE=numeric-column | range-attr-var | expression

I have used google search for:  "sas proc template vectorplot color" and choosed the link above.

Next link is to documentation on SAS color names and color definitions:

see page 12 in the PDF.

Thanks for your help Shmuel, none of it seems to be working. Do you know if I can use multiple GROUP= in the vectorplot? that way I can use lineattrs=(color=xxx) to assign different colors? thanks!

Thanks everyone for their help!

I solved the problem (in bold):

Proc TEMPLATE;
   define STATGRAPH GTL_GRAPH;
   BEGINGRAPH /BORDER=False datacontrastcolor=(purple red blue green);

   LAYOUT OVERLAY /
   YAXISOPTS= (DISPLAY=(LABEL) OFFSETMIN=0.1 OFFSETMAX=0.2 LABEL="Patients"
   LABELATTRS=(FAMILY="Arial" WEIGHT=bold SIZE=11pt)
   LINEAROPTS=(VIEWMIN=1 viewmax=%eval(&viewmax - 3) TICKVALUESEQUENCE=(start=1 end=&viewmax INCREMENT=1)))
   XAXISOPTS=(OFFSETMIN=0.05 OFFSETMAX=0.05 LABEL="Drug Treatment (weeks)"
   LABELATTRS=(FAMILY="Arial" weight=bold size=11pt) TICKVALUEATTRS=(COLOR=BLACK)
   LINEAROPTS=(VIEWMIN=0 VIEWMAX=&maxweek TICKVALUESEQUENCE=(START=0 END=&maxweek INCREMENT=&weekint)));
 *  ENTRY HALIGN=center TEXTATTRS=(FAMILY="Arial" COLOR=black SIZE=11pt WEIGHT=bold) "Dose Cohort: Drug 20mg/d (N=10)"/valign=top ;

The 4 colors you have defined will be used for the classifications instead of the 12 colors defined in the Style.  However, it should be noted the colors will be used in the order the Class values arrive in the data.  If the order of the class values in the data change from day to day, you will get different class values assigned to different colors.  

The safest way to consistently assign colors to class values is by using the Discrete Attributes Map, where they are assigned by VALUE, like "Mild", or "Severe" and not by position in the data.

Sorry, I have almost no experience with SAS GRAPH of any kind.

I have a lot of experience working with SAS and searching for relevant SAS documentation,

and that is what I have done, with hope that you may understand the documentation better than me

and come to the right conclusion.
