they are several issues here: 1) in using ListPlot3D you do not provide X and Y they are assumed by the location in the array 2) you need to provide a 2 dimensional array I suggest you do Show[Graphics3D[ Line [{{1,10,100},{2,20,200},{3,30,300},{4,40,400}}] ]] If you do not want lines you might want to substitute "Point" for "Line" in the command above. That's a pretty boring graphic. I hope it gets better with real data. good luck, Luc. >-----Original Message----- >From: h9302431@hkusua.hku.hk [SMTP:h9302431@hkusua.hku.hk] To: mathgroup@smc.vnet.net >Sent: Wednesday, February 18, 1998 5:32 PM >To: mathgroup@smc.vnet.net >Subject: [mg11037] plot graph > >I have a set of solutions.
