Pure speculation on my part, but it looks like the fitted line starts at x=0, but the data start at x=1. Maybe that's what OP means.

Reading the help for plot would seem to be useful. It would tell you that:
When you use plot with ONE argument, it assumes that the x variable is simply an index vector, 1:length(y).
How can plot possibly know that you wanted it to start at zero? MATLAB does not read your mind, although the mind reading toolbox has been under construction for many years.
