How can i print z axis values on a pcolor plot

15 views (last 30 days)
x = [0,10,20,30], y = [100,210,300,500] z = [0 0 0 1; 0 0 1 0; 1 1 0 0; 1 0 0 0];
i tried generating a pcolor plot for above variables such as
pcolor(x, y,z);colormap summer; colorbar
Now I need to display the z values on the plot for every box displayed in the plot and I havent been able to find a way to do so

Something like this?
[X,Y]=meshgrid(x,y);
hold on;
pcolor(x, y,z);
colormap summer;
colorbar
text(X(:),Y(:),num2cell(z(:)'))

I am not sure I understand. Can you give me a hint? Perhaps an image?
I'm speculating now but perhaps you can replace the last line of code with this:
text(X(:),Y(:),sprintfc('%d',z(:)))
Or do you want to change the fontsize? if so:
text(X(:),Y(:),sprintfc('%d',z(:)),'fontsize',5)
