The x=0 says, that the first column should be the x coordiante, while
the y=0 says, that the second column is the y coordinate. If you make
plots with more axes, you can have x2, x3, etc as well. Certains
styles allow also for other names, like dx for x error bars in the
symbol style.
There is no (not yet) default when ommitting those specifications
needed to use the style. The symbol style needs an x and y value to be
used at a xygraph. Thats the general concept ...
