Hi,
I have the following scatter graph using the commant scatter 3
My x axis is a column vector 3042x1 (utuvals 0-0.6)
my y axis is a column vector 3042x1 (mppvalsco 1.3-2.1)
and z axis is a column vector 3042x1 (vectorrealcolum)
How can i convert the scatter plot to surface plot with the point appearing on it?
Thank you

[xq,yq] = meshgrid(-2:.2:2, -2:.2:2);
vq = griddata(x,y,v,xq,yq); %(x,y,v) being your original data for plotting points
mesh(xq,yq,vq)
hold on
plot3(x,y,v,'o')
xlim([-2.7 2.7])
ylim([-2.7 2.7])
You get the surface plot with points appearing on it, using the above code. You may also refer to the documentation at https://www.mathworks.com/help/matlab/ref/griddata.html
