How to plot the labels of contours

hello,

I would to ask about contours plot in matlab. I am using thefollowing commands in order to plot contours.

t=importdata('input.txt');
x=t(:,1);
y=t(:,2);
z=t(:,5);

[xi, yi] = meshgrid(...
    linspace(min(x),max(x)),...
    linspace(min(y),max(y)));

zi = griddata(x,y,z, xi,yi,'natural');

figure(1)
contourf(xi,yi,zi,15,'LineStyle','none')
set(gca,'ColorScale','log')
colormap(flipud(hot(50)))

The question is how could I plot the labels of the contours in my plot?

could you please help me?

Just use contour and label them

figure(1)
contourf(xi,yi,zi,15,'LineStyle','none')
hold on
[C,h] = contour(xi,yi,zi,15);
dx=20;
% change dx to increase fontsize
clabel(C,h,'FontSize',dx,'Color','red')

set(gca,'ColorScale','log')
colormap(flipud(hot(50)))

You can also define your contour labels. Hope it works

ok thank you very much.

Is there a way to change the fonts of these labels??

@Ivan Mich see the edited answer.

Excuse me, I have a question. I would like to have the same bins and color classification in contourmap and in colorbar. But the point is that I can not make it, despite the search I did.

(for example I would like to have 4 color bins in contour map and in colorbar too)

Could you please help me?
