I think you are looking for a scatterplot.
clear all; close all; clc;
x = rand(100,1);
y = rand(100,1);
z = rand(100,1);
figure();
scatter(x,y,20,z);
xlabel('x');
ylabel('y');
c = colorbar;
c.Label.String = 'z';
grid on;

This should do it.
clear all; close all; clc;
x = rand(100, 1);
y = rand(100, 1);
z = rand(100, 1);
[xx, yy] = meshgrid(x, y);
zz = griddata(x, y, z, xx, yy);
figure()
[~, h] = contourf(xx,yy,zz,10);
set(h, 'LineColor', 'none');
xlabel('x');
ylabel('y');
c = colorbar;
c.Label.String = 'z';
