I wanted to 3D plot my data like shown in attached image.

Answer 1

Use surf() or

doc surf

there are several examples at both locations

I used surf. I got stuck to plot this table in x y z axis.

[Turlough Hughes]

In general, you should include what you have tried so far in the question and attach the data in a format that can be loaded by those answering the question - .mat, .xlsx, etc. Can you do the latter now? Once you've loaded the data into your workspace it will go something like:

[Theta, Distance] = meshgrid(theta,distance);
surf(Theta, Distance, Ratio)

I used:

x=[0.431233185, 0.432959286, 0.305602993, 0.434045431, 0.284004725, 0.363586494, 0.397717881];

y=[3.5, 2.5, 1.5, 0, 1.5, 2.5, 3.5];

z=[68,68,68,68,68,68,68];

tri= delaunay(x,y);

h = plot(x,y,z,varargin{start:end});

X=rand(10,2);

dt=delaunayTrigulation (X);

triplot(dt)

[x,y,z]=meshgrid(1:15,1:15,1:15);

tri=delaunay(x,y,z);

z=peaks(15);

trisurf(tri,x,y,z)

Giving me this error:

>> Untitled

Error using plot

Data must be a single input of y-values or one or more pairs of x- and y-values.

Error in triplot (line 91)

h = plot(x,y,c,varargin{start:end});

Error in Untitled (line 5)

triplot(tri,x,y,z);

Your x and y are only the first column of the table. You need to fill out the entire table to get a 2-D matrix.

Try warp()
