Dear all,
I need help in draw a contour plot. I got a contour plot using the following code:
[c2,h2]=contour(xx(6:300),yy(6:300),Theta_e(6:300,6:300),'--b','LineWidth',0.2,'ShowText','on','labelspacing', 700);
The postion of label in the blue lines are set with 'labelspacing'. But I want the position of the label in the blue lines at the end of the blue lines. I wonder how to do it.
Thanks in advance.

The function "clabel" will solve the issue.
With "clabel(c,h,'manual')" command you can add the label at locations you select with the mouse. For further reference see this link.

You can also use seperate contour plots such that one of those plots only has contour lines on the left. You can then enable labels only for that one. The other contour plot will then not have any labels.

I know this is a very late reply, but I'm adding in case it helps others.
I had a similar problem. If you clabel a contour plot of a matrix Theta_e(i,j), it looks like clabel starts the labels near i=1,j=1. I was able to "trick" clabel into putting the labels on the other end of the contour lines with something like
[c,h]=contour(flipud(xx),yy,fliplr(Theta_e),10,'w');
clabel(c,h,'LabelSpacing',700,'FontSize',13,'color','white');
Your might have to play with different combinations of flipud() and fliplr() on the inputs to get the contour lines correct. Hope that helps.
