3d contour plot in MATLAB

Hi,

I want to plot 3D contour in MATLAB. I have three dimensions (X, Y,X) and value of each value in specific grid.

Please help.

I have attached sample data set for the same.

To read your data:

[my_data headers] = xlsread('test data.xlsx');

But you present 4D data: 3 coordinate and value. Yo have to choose what to plot against what. For example:

>> x=my_data(:,1);
>> y=my_data(:,2);
>> z=my_data(:,3);
>> tt=my_data(:,4);
>> plot3(x,y,tt)

>> tt2=reshape(tt,51,121);
>> contour(x(1:51),y(1:121),tt2')

I want to plat tt data for every value of X, Y and Z.
