How can I display text on pcolor map like in the image below?

How can I display these numbers on my pcolor map?

Answer 1

L = membrane(1, 100);
s=pcolor(L);
s.EdgeColor='none';
set(gca, 'YDir', 'reverse')
xl = xlim;
yl = ylim;
n = 1;
xy =[];
for i=1:7
    iodd = mod(i, 2);
    for j=1:7
        jodd = mod(j, 2);
        if (iodd && ~jodd) || ~iodd && jodd
            xy = [xy; j, i];
        end
    end
end

%map to xlim and ylim
xy(:, 1) = xl(1) + xy(:, 1) * diff(xl)/8;
xy(:, 2) = yl(1) + xy(:, 2) * diff(yl)/8;
text(xy(:,1), xy(:, 2), string(1:24))

If you have your text-strings and their respective location you should be able to do this brute-force:

pcolor(X,Y,Z),shading interp
x4t = randn(1,23); % positions just for this example
y4t = randn(1,23); % rather stupid locationing of text
text4labels = 'a':'w'; % not much of information either
fntsz = 15;
fntw  = 'bold'
for iT = numel(text4labels):-1:1,
  thl(iT) = text(x4t(iT),y4t(iT),text4labels(iT),'fontsize',fntsz,'fontweight',fntw);
end

You'll have to modify the locations and texts to produce anything sensible.
