What makes you think it's "not good"?  I checked against the
implicit plot, and it looked quite correct.

The way to fake an implicit curve plot in gnuplot is this:

	set view map
	set contour base
	set cntrparam levels discrete 0
	unset surface
	set isosamples 30

	splot sqrt(x)+sqrt(y)-1

For good results, you'll have tune the x and y ranges a bit.
