How to make graph with smooth edges?
I am making graph using origin, and I have a problem. My graph looks something like letter Z and i want it to have smooth edges. Is there any way to do it in origin?
It is pretty complicated.
You can draw it in an Excel X-Y Chart. Excel has a smooth curve option.
To do it yourself you need a rather complex technique called “Polynomial Interpolation”.
This explains how, but you need to be very comfortable using Algebra first.
