oh, i could put labels on contour levels, but these labels are so litle and unreadable. how do i can set background color to them??

[Fangjun Jiang]

The background color of the label, or the contour figure?

[Fangjun Jiang]

Get the handle of the label and set the background color.

handle=clabel(...);

get(handle(1),'backgroundcolor');

set(handle(1),'backgroundcolor','green');

You can also specify 'labelspacing' when calling clabel().
