3-D graphs - comp.soft-sys.sas

Hi everyone, I am trying to plot a 3-D graph. I have 3 variables and I need to represent those point in a 3-D graph, Can anyone help me please??? Thanks in advance. Miguel. --------------------------------- Correo Yahoo! Comprueba qu� es nuevo, aqu� http://correo.yahoo.es

ok, then... I have a file with names of people and 3 variables to describe each person (var1, var2, var3). I am trying to plot a 3-D plot, the axis X with var1, axis Y with var2 and axis Z with var3. So my intention is to see in the same plot. I tried, proc gplot; plot x*y=z; run; quit; but it is a bidemensional graph, I need to build 3 dimensions. Many thanks. Miguel. bill_droogendyk@dofasco.ca escribi�: Miguel; always helpful to give us more explanation of what it is that you are trying to do. My guess would be that you could use .. proc gplot; plot x*y=z; run; quit; Look for examples at www.sas.com under tech support -----Original Message----- From: SAS(r) Discussion [mailto:SAS-L@LISTSERV.UGA.EDU] On Behalf Of Miguel de la Hoz Sent: 08 November, 2005 16:44 To: SAS-L@LISTSERV.UGA.EDU Subject: 3-D graphs Hi everyone, I am trying to plot a 3-D graph.

You will need to use PROC G3D to get the graph you are looking for. The only problem with G3D is that it will plot only the highest Z value for same combinations of X and Y. This can be solved by adding a small fuzz value to the X or Y values before plotting. So, try something like the attached code. I will let you look at the options in the documentation to set up plot options. Some of the options you can play around with is to set different size of symbols based on values of another variable. If there are many points to plot, I am not sure if this plot will look good. Give it a spin (use at your own risk): %let options=; %macro threedscat(data,xvar,yvar,zvar); data _null_; set &data end=eof; retain minz 9E6; minz = min(minz,&zvar); if eof then call symput('zmin',put(minz,best12.)); run; data prep; set &data; retain increment 1; if &zvar > &zmin then do; &xvar=&xvar + 1E-6*increment; increment=increment+.01; end; proc g3d data=prep; scatter &yvar*&xvar=&zvar / &options ; run;quit; %mend; Jonas V.

Be sure and try the ACTIVEX gdevice for these if you're on a windows platform, and use ODS to output HTML. Doing so gets you the ability to rotate the point cloud interactively w/your mouse. I just love that... -----Original Message----- From: SAS(r) Discussion [mailto:SAS-L@LISTSERV.UGA.EDU] On Behalf Of Jonas Bilenas Sent: Wednesday, November 09, 2005 4:45 AM To: SAS-L@LISTSERV.UGA.EDU Subject: Re: 3-D graphs You will need to use PROC G3D to get the graph you are looking for.
