Hello to all !
I'm new at Matlab and bad at coding, and I need to plot a 3-axis graph. I actually have 3 excel tables that I need to arrange in 3D plot.
So far, I managed to create a 3D plot by replacing my qualitative variable by a quantitative variable, and it works. Here's my code and my plot:
data=importdata("essaidata1.xlsx")
x=data(:,1);
y=data(:,2);
z=data(:,3);
scatter3(x,y,z,'*','g')
xlabel('Taille Latérale (nm)');
ylabel('Epaisseur');
zlabel('C/O ratio');
hold("on");
data=importdata("essaidata2.xlsx")
x=data(:,1);
y=data(:,2);
z=data(:,3);
scatter3(x,y,z,'*','c')
hold("off");
hold("on");
data=importdata("Essaidata3.xlsx")
x=data(:,1);
y=data(:,2);
z=data(:,3);
scatter3(x,y,z,'*','r')
hold("off");
What I would like to do is replacing my C:O ratio (my Z axis) by a class. Instead of a ratio , I would have different class on matarials "material 1", "materail 2", "material 3" . When I try to replace the numbers by the material type directly in my exce data, I have this error :
data =
data: [6×2 double]
textdata: {6×1 cell}
rowheaders: {6×1 cell}
Index in position 2 exceeds array bounds (must not exceed 1).
