I have made a 3D-plot using 'meshc'. I want to adjust the placement of the labels on the contour lines.

The handle return by the 'meshc' is

h = 
2x1 graphics array:
  Surface
  Contour

Hence, I used the following commands to display the labels.

hContour=h(2);
hContour.ShowText='on';

The labels are too crowded. I want to manually adjust their location and the font size.

Hey Ibrahim,

have a look at Contour Properties - the LabelSpacing property might help. Also you can specify your own contour levels (see the Contour Levels property group) which might be used to control the labels indirectly.

Greetings, David

I want a single label per contour line. The placement of the labels should be such that they do not overlap and clearly represents the line they belong to. I have used 'LabelSpacing' but it doesn't solve the problem.

hContour.LabelSpacing=600; % Default (144)

I have attached the image to make it clear.

Use the clabel function for full control on the lines & labels. With the current plot you cannot achieve your goal. If you want to keep the current lines, a workaround maybe to use a colorbar with color levels matching exactly your contour levels and then label the colorbar accordingly.
