I have a list of 10 points ( Voltage=f(Current) ) measured by
multimeters. I interpolated them with linear fit.vi. Now I have
to extrapolate this line to find the offset of current and voltage. How is this possible with labview?
Linear fit.vi returns Slope and Intercept. With those you can evaluate the equation of the line (y = m*x+b) to find what you want. The Intercept value itself may be the offset you are looking for.
