Hi,

I want to display a figure (x-section; xz-plan) in white and black, instead of colors.
How? Thank you for your help.

I don't know the meaning of "(x-section; xz-plan)"
If you are plotting a surface using functions such as pcolor, imagesc, or surf then (assuming you want grayscale, not B&W) just do:
colormap gray

If you have a line plot then type
help plot
