Can we specify colour range for a surface plot in proc g3d?

[ Edited ]

Is there a way that we can specify or assign a specific colour to a particular range of absolute values in a surface plot in proc g3d

eg :

rangeattrmap name="yield_map";

range 0-8 / rangecolormodel = (black );
range 8.02-8.88 / rangecolormodel=(darkred);
range 8.88-9.74/ rangecolormodel=(red);
range 9.74-10.6 / rangecolormodel=(yellow);
range 10.6 - 11.46 / rangecolormodel=(green);
range 11.46-12.32/ rangecolormodel=(darkgreen);
endrangeattrmap;

 or 

specify colours using "if - then - else" type of statments

 

without implementing a large number of macros as in eg : https://communities.sas.com/t5/SAS-GRAPH-and-ODS-Graphics/Is-it-possible-to-specify-x-y-and-z-axis-l...

 

I also want to specify the length and range of the x y and z axes in the surface plot such that it looks rectangular like my data.

my  code is :

 

ods _all_ close;
ods html file="/home/amrit.genetics0/created for HTML output/s25264new.htm";

/* Set the DEVICE on the GOPTIONS statement */
/* to ACTIVEX. */
goptions reset=all device=activex
border xpixels=600 ypixels=400
cback=white;


Data surface_data;
input longitude latitude yield;
datalines;

Re: Can we specify colour range for a surface plot in proc g3d?

I'm not sure about controlling that with device=activex, but I don't think there's a way to control the color of the g3d surface plot like you're wanting in the traditional g3d surface plots. If you use a scatter plot rather than a surface plot, you can get something fairly close ...

 

proc g3grid data=SURFACE_DATA out=GRIDDED;
grid LONGITUDE*LATITUDE=YIELD / spline smooth=0.01
axis1=1 to 25 by .5
axis2=1 to 13 by .5;
run;

data gridded; set gridded;
length colorval $12;
if yield<=8 then colorvar='black';
else if yield<=8.88 then colorval='darkred';
else if yield<=9.74 then colorval='red';
else if yield<=10.6 then colorval='yellow';
else if yield<=11.46 then colorval='green';
else colorval='darkgreen';
run;
proc g3d data=GRIDDED ;
scatter LATITUDE*LONGITUDE=YIELD /
shape='balloon' color=colorval rotate=25 /*noneedle*/
grid zmin=0 zmax=20 zticknum=5;
run;

There is a very old example (from the V6 SAS/Graph Examples book) that shows how to annotate a colored surface plot onto a set of g3d axes, that you might could modify to produce what looks like a colored surface plot:
