MATLAB: 2D scatter plot with Z-value in color

Question

Hi all,

It’s a basic question but I struggle to find the answer on the Internet…

I have a matrix with x,y and z colum, representing the c-coordinate, the y-coordinate and depth (z).

I’d like to plot (x,y) but that those points show a colorscale depending on the depth value (just the point colors I don’t want an interpolation).

Can somebody help me please?

Answer 1

pointsize = 10;
scatter(x, y, pointsize, z);
