Hi all,
I am trying to link these 3D lines through a surface that pass through all of them, which basically will show the variation between them and it would be great if that will be colored. I attached a pic that clarify my thoughts, and hopefully I will get help!
I tried to use the griddata command but unfortunately it didn't work.
I also attached my code and excel sheet I am working on.
Thanks,
clc
close all
clear all
dataset =xlsread('test.xlsx','N','G1:L203');
D1=dataset(:,2);
F1=dataset(:,1);
F2=dataset(:,3);
F3=dataset(:,5);
colormap hsv
figure(1)
plot (D1,F1,'MarkerSize',15);
hold on
plot (D1,F2,'-','MarkerSize',15);
plot (D1,F3,'--','MarkerSize',15);
hold off
z1=3*ones(201,1);
z2=6*ones(201,1);
z3=9*ones(201,1);
XX = [D1;D1;D1];
YY = [F1;F2;F3];
ZZ= [z1;z2;z3];
Dlin = linspace(min(D1),max(D1));
Flin = linspace(min(F1),max(F3));
Zlin = linspace(min(z1),max(z3));
[X,Y] = meshgrid(Dlin,Flin);
figure(2)
plot3(D1, z1, F1,'-.')
hold on
plot3(D1, z2, F2)
plot3(D1, z3, F3,'--')
grid on
figure(3)
Z= griddata(XX,YY,ZZ,X,Y);
plot3(X, Y, Z);
grid on
axis tight
view(-50,30)

You are concatenating in a wrong way
XX = [D1 D1 D1];
YY = [F1 F2 F3];
ZZ = [z1 z2 z3];
surf(XX,ZZ,YY,'EdgeColor','none')
