Specify colours for a variable in proc g3D surface plots

[amrit11]

How can I specify colors for the 3D surface plot based on response values  ? I want same colour to appear if the values are in the same range, for multiple graphs.

my code is :

ods _all_ close;
ods html file="/home/a.g/created for HTML output/new.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;

One way is to adapt the number of colours to the range of your data.

data SURFACE_DATA;
  set SURFACE_DATA;
  YIELD2=YIELD*2;       
run;

axis order=(0 to 50 by 5);

goptions colors = ( blueviolet blue aquamarine green);
proc g3d data=SURFACE_DATA ;
  plot LATITUDE*LONGITUDE=YIELD / style=4 contour=1 grid zaxis=axis1;
run;

goptions colors = ( blueviolet blue aquamarine green yellow orangered red );
proc g3d data=SURFACE_DATA;
 plot LATITUDE*LONGITUDE=YIELD2 / style=4 contour=1 grid zaxis=axis1;
run;
