Obviously the labels in the Excel chart are wrong and should be exchanged.

Prime can also find a regression fit (a different one than shown in the Excel plot) for you.

Like this.

(See attached Prime 4 file)

Explanation:

Mathcad is NOT a spreadsheet program. It's more like mathematics. In your case p is/should be a function. I defined it a function of parameter epsilon.1 (because you had used that in the exponent). Note that this epsilon.1 is now unrelated to the epsilon.1 you defined to be 0.0515 just above p.

Now I assumed that you wanted to plot epsilon (from the table in the upper left) versus p (as a function of this epsilon) so I changed the expressions along the axes of the chart accordingly.

 

Success!

      Just a remark:

      If we omit the first data line (with epsilon and p zero) we get similar results as shown in the Excel image if apply a linear regression on the logarithmized data.
