3D surface plot from 3 columns of excel data?
显示 更早的评论
Total newbie here.
I have 3 columns of data and I want to create a 3D scatter plot. I was able to impot the columns as three 18 x 1 cell arrays in m y workspace. Can anyone help with some basic steps? Thanks!

The first basic step is the enter doc scatter3 in the MATLAB command window. In the documentation presented, you'll find several examples that should help you get started. Good luck.

Attach your data. It depends on whether data is stuctured or unstructured.

Well, in that case, it might help if you posted your data and any code you've written so far.

thanks again. this is what I imported
I tried the following commands:
plot (a,b,c)
surface (a,b,c)
I know this must be trivial, but this is my first time using Matlab

Here you go...
T = readtable('https://www.mathworks.com/matlabcentral/answers/uploaded_files/645855/P3%20data.xlsx');
x = T{:,2}; % Speed
y = T{:,3}; % Range
z = T{:,4}; % Cost
scatter3(x,y,z);
xlabel('Speed');
ylabel('Range');
zlabel('Cost');
