Hi and thanks in advance to everyone who will be able to help me. I have 2 independent lognormal distributions with different means and sd. I want to plot them togheter in a 3D plot. How can i do this??? I'm getting crazy... Thanks Ale -- View this message in context: http://r.789695.n4.nabble

Edwin, the problem is that the underlying R code treats the "lab" argument as something that should be approximate in some way. In your case, you can say, e.g.: par(lwd=3) scatterplot3d(. lab= c(5,hostLength*2), .) Best wishes; uwe Edwin Sendjaja wrote:

Hi Uwe, I decided to use scatterplot3d, because it looks better. I have some questions: Is it possible to get 1 axis( for example: z-axis) not as numeric, but as character. Because I have date set like this: x=relative Time: 0,3 ms; 0,5ms, etc y=Delay:10 ms, 20 ms, etc z= Host: cnn.com, heise

Hi Uwe, Thanks for your answer. What is the different between rgl and scatterplot3d? I dont need a graphik like vulcano. I just need 3D-"dot"-plot. Am Donnerstag, 17. April 2008 09:03:17 schrieb Uwe Ligges: > Edwin Sendjaja wrote: > > Hello, > > > > I've got some problems. I hope someone can
