Can origin 8 read tanh ? I have the curve fitting and everything are ok but when I am going to put my function in the book in a columm
after I choose set columm values and when I am writing the function with the variables that I have found from the fitting (I leave only x and y as x and y) the columm remains blank. Why? |

You just want to type the expression:
90,21673*(tanh((Col(H)-14,5996)/42753,35153))-0,00176*Col(H)+0,42223
You should see the col(m.raw) above where you enter the expression.

Thank you my friend for the support, I did it I changed x and y like you said me but nothing. This is the equation:
a) Previous
Y=90,21673*(tanh(X-14,5996)/42753,35153))-0,00176*X+0,42223
b) Later
Col(m.raw)=90,21673*(tanh((Col(H)-14,5996)/42753,35153))-0,00176*Col(H)+0,42223

Instead of using X and Y, you need to replace with the col( ) function for the columns assigned as X and Y. You can click on the Col(A) menu.
