I thank you very much for your prompt answer,
but I don't really understand all mathematical concept there is behind... Indeed I'm a French chemist and I'm not very used to use Maple software.
I tried to modify the code to represent my 3 experimental variables
> IC50 := [5, .5, .6, 1.5, 1, 3, .8];
> REDOX := [.2, .41, .52, .72, .69, .56, .38];
> LIPO := [.572, 2.233, 1.966, 2.107, 1.919, 1.008, 2.345];
> s := NULL;
> for i to nops(IC50) do s := s, [LIPO[i], REDOX[i], IC50[i]] end do;
> pts := [s];
> pointplot3d(pts, axes = normal, axis = [color = grey], axis = [color = red], thickness = 3, font = [HELVETICA, BOLD, 11], title = "Correlation IC50 REDOX LIPOPHILIE", color = blue, symbol = sphere);
but I think there's no difference in the representation. Isn't it?
1) I tried to add label in pointplot3d function, but Maple returns an error.
> pointplot3d(pts,axes=normal, axis=[color=grey], axis=[color=red],thickness=3,font=[HELVETICA,BOLD,11],title="Correlation IC50 REDOX LIPOPHILIE", color=blue,symbol=sphere, labels=['REDOX,'IC50','LIPO']);
Error, unable to match delimiters
2) I copy/paste the procedure from Herclau (without understanding so much....) but this don't give me a graph...? isn't it?
I read the help file for the function CurveFitting[ArrayInterpolation] and I think this could help me to draw my graph. But I really don't understand how to use it with my variable given that each variable is independant from another. The result of my 3D map should be a kind of sink.
Thank you for your help.
