- Use imagesc, hold, and contour;
- Use the contourf (fills the contours) function only on (x,y,z).
Contour lines on a imagesc plot

Hi,
I am plotting a imagesc with (x, y, Z). On top of that I would like to plot the contour lines with constant values of z. Could you please help me with it? Thanks a lot in advance.

There is not enough information in your Question to provide a definite Answer.

You can specify the contour line locations in contour and contourf:
contour(x, y, z, [0.1 0.2 0.3 0.4])
Extend the vector (or use the colon operator or linspace to create an equally-spaced vector) to as many contour lines as you want,at whatever level you want. Contour lines that are out-of-range will of course not be plotted, but they will not throw an error.
See the contour documentation for details.
