Hi, I've just spent an afternoon trying to make an <bf>isometric</bf> (x y z axes are displayed with correct scale ratio corresponding to a viewing angle, so that the plot of a cube looks like a cube and not cuboid on the plot ) 3D plot using 'splot' and I could not find a quick solution  does anyone know a way of getting that sort of plot except for setting equal ranges of x and y axes? Thx

Sorry mate, as I understand it gnuplot outputs depend on the term that you use. So even if you get your square to look right in one terminal it can still look poo in another. I guess you just have to play around with set size or whatever until it looks right in your environment. > Subject: [Gnuplotinfo] Isometric 3D plot in gnuplot > > Hi, > > I've just spent an afternoon trying to make an > <bf>isometric</bf> (x y z axes > are displayed with correct scale ratio corresponding > to a viewing angle, so that > the plot of a cube looks like a cube and not cuboid > on the plot ) 3D plot using > 'splot' and I could not find a quick solution  does > anyone know a way of > getting that sort of plot except for setting equal > ranges of x and y axes? > > Thx > > > __________________________________________________ Do You Yahoo!?

But it is a 3D isometric plot that I'm talking about, which apparently is not yet supported by gnuplot. > I guess you just have to play around with set size or > whatever until it looks right in your environment. That is what I've been doing so far and it really sucks  I had to plot few tens of plots of different sizes and after few hours of struggle I just let it go  I've done it in scilab. But I would rather do that in gnuplot .... Have you got any other suggestions?

The usual gnuplot way of doing that would be 'set size ratio 1'. Try it.

Try it. 'set size ratio 1' works only for 2d plot but not for 3D plot. This seemingly trivial question is not so trivial  gnuplot simply does not support isometric 3D plots! It is something for the gnuplot gurus to think on. I could get x and y axis to be isometric only by setting equal x and y ranges  but then I had to play with z axis scaling, which was not elegant and took lots of time. Anyway, the x and y dimensions of the plots I want to make are not equal, so cannot jump over it this way. Any more suggestions anyone? I would really apreciate a solution. K
