Hi Mike
This forum is for documentation errors rather than help; you need to use the
users forum for this sort of question.
However, in principle, a float is in a paragraph which can be centred and a
figure can be centred within a float. If you want more detailed control, put
the image in a minipage (box) in the float and then you can add spaces to move
the material around in the minipage.
If you are using LaTeX directly, then pstricks is the normal way to create the
sort or figure you want. In LyX I normally create the graph in another program
and then import it as an image. Depending the layout of the maths and the size
of the image, you can import it as an inline image, an image in its own
paragraph, an image in a float or an image in a minipage (box).
However, you may get a more informed and enlightening answer if you use the
users forum.
