I have just installed gnuplot but am not able to figure out how to plot
y=x^2-5x+6 ! tutorials tell how to plot bessels functions etal

Hi!

Try with:

gnuplot> plot (x**2 - 5.0 * x + 6.0) with lines

or

gnuplot> f(x) = x**2 - 5.0 * x + 6.0
gnuplot> plot f(x) with lines

For further examples see

gnuplot> help plot

Cheers,

Hernán

gnuplot> f(x) = x**2 - 5*x + 6
gnuplot> plot f(x)

It's a bit hard to believe that isn't covered in the tutorial...

Write that expression properly, in something reading more like a 
programming language rather than typical mathematical shorthand 
notation, and it'll just work:

	plot y**2-5*x+6

To see why this works, read "help plot" and "help expressions", thoroughly.
