gnuplot for dummies: sin(x) is nice, but...
Hi there. My problem is that I can't figure out how to use gnuplot very basically, and I can't seem to find such info in the tutorials.
What I want to know:
* plotting a line.
* plotting a plane (I know about splot)
I know the basic syntax is plot "something" for example, plot sin(x) . Sine looks pretty, but how do I get a regular boring line, of y=mx+b form? And a regular boring 3d plane.
