Hi there. I have a problem with this. I'm trying to plot a polynomial fit done with origin 8.5 on mathematica. The thing is that the polynomial plot I get in mathematica from the coefficients given in originlab don't match, and I don't know why. I'll let you some pics of what I'm trying to do, the first one is the fit on origin lab, the second the tabs with the coefficients, and the third the plot on mathematica. I also draw two circles in the part of the graph which makes clear the differences between one plot and the other.

What could be happening? is that the software isn't working or did I made any mistake when going from origin to mathematica?

I tried to replace the exponential basis from 10 to e, but that makes it look even worse.

Bye there, and thank you in advance.
