Contour with proper scale

Hi

I plot my contour but unfortunately it does not show enough line.

How can I increase the line (and decrease difference of line value ).

Attached there is an example. temperature difference of the lines is 5 C.

How can I decrease it to 2 C?

You ccan specify the number of contours you want (see Contours at Twenty Levels), and also their levels by providing a vector of the levels (the vector must contain two or more values, to draw contours at one level, the two values must be the same).
