You can't have it persist, since all variables inside functions are
local.  On the other hand, you can have it return a value that you
wish to use later on, such as x and y from your plotgraph function.

In your lobf function, simply call plotgraph like this:
[x, y] = plotgraph( file, "*" );

and x and y will be what is returned by plotgraph.
