%读取excel数据，同目录下
tx=xlsread('co.xlsx');
tx(:,1)=[];
tx(32,:)=[];
z=tx;
figure(1)
pcolor(z)
shading interp;
colorbar; colormap(jet);
xlabel('W1');ylabel('W2');
hold on;
title('C0')
contour(z,[0.8 0.5 0.25 0.1],'b--');
clabel(z,'LabelSpacing',1, 'FontSize', 10, 'Color', 'k');
hold off;

It is my understanding that you want to label those data points [0.8 0.5 0.25 0.1] over your contour plot.
There is a property named ‘ShowText’ which needs to be set to ‘on’ in order to achieve that. So, you need to pass this name-value pair to you contour function as an argument to get those points labelled on your plot.
I have attached a link below which has a very similar example of how to pass that property to the contour function:

Hope it helps!!
