Plot data with time axis

Hello.

I have a function that takes data (one each minute) from serial port an plot them in a figure. At the moment, axis are number of samples, but I would like to have time (in format hh:mm). How could I do it?

while(1)

   data =fscanf(s); 
   numValue=str2num(data);
   v=numValue*5/1024;
   tempK=v*100;
   tempC=tempK-273;
   if(numWindow<sizeWindow+1)
       window(1,numWindow)=tempC;
       numWindow=numWindow+1;      
   else      
       for i=1:sizeWindow
          tempFiltered=tempFiltered+window(1,i);
       end
       tempFiltered=tempFiltered/sizeWindow;
       x =[x tempFiltered];
       plot(x);
       drawnow;
       disp(tempFiltered);
       tempFiltered=0;
       numWindow=1;
   end  
end

This file exchange post might help. It shows how to use date/time as your X-axis.

You can ignore the stuff that does not relate.

Hope this helps -Ankit
