How to make a grid plot with 3 parameters

Hi everyone,

May some one help me,

I have data in (x,y,x). I want to plot z in teh grid of x,y with a shift of 0.01

(Detail: I have 85000 values for x, y and Z. Where x is ranging from -129.0 to -131.0 and Y is 45.0 to 47.0. I want to plot teh values of z in a grid of x,y with an increment 0.1 for both x and y.

For example, zone 1 (-131.0 to -130.9, 45.0-45.1) include the z-values for this region and so on.

Data is presented as below:

See griddata(): https://www.mathworks.com/help/releases/R2020a/matlab/ref/griddata.html

For example,

X = %[85000x1] vector
Y = %[85000x1] vector
Z = %[85000x1] vector

[xq, yq] = meshgrid(-129:0.1:-131, 45:0.1:47);

zq = griddata(X, Y, Z, xq, yq);

surf(xq, yq, zq);

Thank for guidence. I required reuslts in 2D so that I can do further analysis for each grid.

[Ameer Hamza]

The xq, yq, and zq are 2D grids. Can you explain how do you want the results differently?

I want to plot the z point in x-y grid as a scatter data after that I will to futher analzye teh data points in each grid

[Ameer Hamza]

Can you show an example of what is the expected output? Do you have an example figure?

unfortunatly, i did not find anything like this, but let me calculate the whole data thenI will back to you
