Curve Function
The function tag allows you to specify the curve to be -plotted as a formula that gnuplot can understand. Be careful using this -tag - it is surprisingly easy to give gnuplot a function it cannot deal +plotted as a formula that gnuplot can understand. Be careful using this +tag. It is surprisingly easy to give gnuplot a function it cannot deal with properly. Be explicit: 2*sin(2*3.141592*x/4) will work but 2sin(2*3.141592x/4) will not. If you do not receive any errors in the gnuplot data but still do not have an image produced, it is likely there
