reversing axis values in PROC TEMPLATE yaxisopts statement

rbettinger — Wed, 03 Aug 2022 16:55:29 GMT

I want to use PROC TEMPLATE to produce a 3D graphic of a surface. I have the following definition, which works properly:

proc template ;
define statgraph surfaceplot ;
begingraph ;
layout overlay3d / cube=false xaxisopts=( griddisplay=on ) yaxisopts=( griddisplay=on ) zaxisopts=( griddisplay=on ) ;
surfaceplotparm x=y y=x z=z / colormodel=( Blue Green Red ) colorresponse=z surfacetype=fillgrid ;
endlayout ;
endgraph ;
end ;
run ;

How do I specify, using yaxisopts, that I want the values to be reversed, e.g., from 10 to 0 on the y-axis which represents the depth dimension, to instead run from 0 to 10?

Have you tried the reverse=TRUE option in YAXISOPTS?

Thanks for a prompt reply.

I checked the online documentation for general axis options for LAYOUT OVERLAY3D and did not find any reference to 'reverse='. There is, however, a 'reverse=true' option for general axis options for LAYOUT OVERLAY.

I get the following error:

ERROR 22-322: Syntax error, expecting one of the following: DISPLAY, GRIDATTRS, GRIDDISPLAY, LABEL, LABELATTRS, LINEAROPTS,

LOGOPTS, OFFSETMAX, OFFSETMIN, TICKVALUEATTRS, TIMEOPTS, TYPE

in the following code:

proc template;
define statgraph surfaceplotparm;
begingraph;
entrytitle "Surface Plot of Lake Bed";
layout overlay3d / cube=false xaxisopts=(label='Length of Lake') yaxisopts=( reverse=true ) ;
surfaceplotparm x=length y=width z=depth ;
endlayout;
endgraph;
end;
run;

so I may just have to get creative to produce the results that I want.

The solution to my question is to be found here: https://support.sas.com/kb/24/859.html.

The description is: "This sample uses PROC G3D to reverse the values on the Y axis. The sample code multiplies the Y data values by -1 in order to reverse the axis order. A user-defined format is then created with PROC FORMAT to format the new Y axis values back to their original values."

Of course, it also works for the PROC TEMPLATE layout overlay3d surfaceplotparm case, too. The sample code is attached.

@rbettinger @svh

I've just had the same problem.

My not so elegant solution multiplies by -1 and then uses tickvaluelist and tickdisplaylist.

proc template;                        /* surface plot with continuous color ramp */
define statgraph SurfaceTmplt;
dynamic _KMS _AGE _Z _Title;              /* dynamic variables */

 begingraph;
 entrytitle _Title;                   /* specify title at run time (optional) */
  layout overlay3d / tilt=30
          xaxisopts=(label="kms" linearopts=(tickvaluelist=(0 30000 60000 90000 120000 150000 180000 240000 300000 )) )
          yaxisopts=(label="age" linearopts=(tickvaluelist=(-12 -24 -60 -84 -108 -120 )
                                             tickdisplaylist=('12' '24' '60' '84' '108' '120')))
          zaxisopts=(label="sales result" );
      
  
    surfaceplotparm x=_KMS y=_AGE z=_Z /  /* specify variables at run time */

       name="surface" 
       surfacetype=fill
       colormodel=threecolorramp      /* or =twocolorramp */
       colorresponse=_Z 
       reversecolormodel=true;
    continuouslegend "surface";

    
  endlayout;
endgraph;
end;
run;
