MATLAB: How to change the font and the size of labels on contours

clabelcontourfontlabel;plotsize;

hi friends

I have a question about labeling and changing the font size. I used the following commands to crate label on contours:

hold on

h = [findobj(gcf,'type','patch'); findobj(gcf,'type','line')];

cs = zeros(2,0);

for k=1:length(h)

cs = [cs [get(h(k),'UserData') get(h(k),'XData').';

length(get(h(k),'XData')) get(h(k),'YData').']];

end

clabel(cs, h)

Now for changing the font and its size what should i do??? What command i should add to the above code?

if you know please answer to my question as simple as you can.

thanks a lot

See the third example on the documentation page for CLABEL for one technique you can use. You can also call CLABEL with an output argument and directly set properties on the text (or line) objects it returns.

I don't know any way directly. All I can suggest is to look at contour.m to see if you can make you own. Share with us if you do find a way.

Find this interesting note in contour.m. Might it give you some leads? The function is in clabel.m

t=0:0.1:7;
y=sin(t);
z=cos(t);
plot(t,t,'r',t,y,'g',t,z,'b',t,y+z,'k');
Strings={'line','sin','cos','sin+cos'};
LabelLine(gca,Strings);
function LabelLine(h_axes,LabelStrings)
h_line=findobj(h_axes,'type','line');
n=length(h_line);
for k=1:n;
    XData=get(h_line(k),'XData');
    YData=get(h_line(k),'YData');
    Ind=round(length(XData)/2);
    text(XData(Ind),YData(Ind),LabelStrings{n-k+1});
end

MATLAB: How can one adjust the format of the numbers displayed on a contour plot using clabel and a vector specifying the levels of the contours

Notice this part of clabel:

text_handles = clabel(...) returns the handles of text objects created by clabel. The UserData properties of the text objects contain the contour values displayed. If you call clabel without the h argument, text_handles also contains the handles of line objects used to create the '+' symbols.

So to get the format you want, call clabel and record the handles, then loop through the handles fetching the UserData, formatting that number as desired, and set() the String property of the text handle to the new string, possibly also setting the Interpreter property as well if you want to use LaTeX superpositioning for the exponents.
