MATLAB: 2d filled contour plot

2d contour plot

I have an x and y data coordinates of an l shaped plate and z data of corresponding displacements and each matrix is 23 rows.
can anyone help me draw a 2d filled contour plot
x = [0;0.03;0.03;0.01;0.01;0;0.02;0.02;0.01;0;0.01;0.02;0.015;0.005;0.025;0.03;0.025;0.01;0.005;0;0.01;0.005;0]
y = [0;0;0.01;0.01;0.04;0.04;0;0.01;0.025;0.025;0;0.005;0.01;0.005;0;0.005;0.01;0.0175;0.025;0.0125;0.0325;0.04;0.0325]
z = [0.002071017;0.002090221;0.001384402;0.001358957;0;0;0.002078694;0.001373731;0.000432053;0.000422168;0.002069412;0.001727074;0.001369789;0.001713017;0.002084764;0.00173648;0.00137873;0.000855225;0.000414625;0.001187851;0.000125043;0;0.000124721]

Best Answer

Try this: 
x = [0;0.03;0.03;0.01;0.01;0;0.02;0.02;0.01;0;0.01;0.02;0.015;0.005;0.025;0.03;0.025;0.01;0.005;0;0.01;0.005;0];
y = [0;0;0.01;0.01;0.04;0.04;0;0.01;0.025;0.025;0;0.005;0.01;0.005;0;0.005;0.01;0.0175;0.025;0.0125;0.0325;0.04;0.0325];
z = [0.002071017;0.002090221;0.001384402;0.001358957;0;0;0.002078694;0.001373731;0.000432053;0.000422168;0.002069412;0.001727074;0.001369789;0.001713017;0.002084764;0.00173648;0.00137873;0.000855225;0.000414625;0.001187851;0.000125043;0;0.000124721];
N = 15;
xv = linspace(min(x), max(x), N);
yv = linspace(min(y), max(y), N);
[X,Y] = ndgrid(xv, yv);
Z = griddata(x,y,z,X,Y,'linear');
figure
contourf(X, Y, Z, 'ShowText','on')
xlabel('x')
ylabel('y')
Change ’N’ to get different results.
