Converting tabulated data to 3D plot

Hi,

I have the attached table. I would be grateful if you can tell me how to show it in 3D ( Red--> x ; Green--> Y & White cells-->Z)

Thanks, Ehsan

Hi,

define a vector x

x = [0 10 30 60 120 -10];

define a vector y

y = 1000:1000:7000;

and calculate/write your z values in a matrix z = [size(y), size(x)].

In this example i use random integers:

z = randi(100,length(y),length(x));

Then use the surf function:

surf(x,y,z)

to get a 3D surface plot from your data.

Note that this procedure sorts your vector x in ascending order. if you want to avoid this, use:

surf(z)

and change the values that are used for the labeling of the axes by using your values from x and y.

Best regards

Stephan
