Table/Figure numbering

[Leonid Belostotski]

Hello,

It was probably discussed somewhere but I was not able to find it.

For my thesis, each figure/table has to be numbered in the following
fashion: Y-X, where Y is the chapter number and X is the figure number in
the chapter. I need to be able to cross-reference to the table/figure and
the list of figures/tables has to follow the same format.
Is there a way of doing it?

Thank you
