If you want a fitted line to be straight on a semilog plot, you need to fit
the data to an exponential trendline. A linear fit curves downward due to
the shrinking of the scale at the top of the log scale.

Hi Jt,

If by semi log you mean log scale on the x axis and natural scale
on the y axis or vice-versa, then right click on one of your data
points click add trendline and select logarithmic. This should
give you a line of best fit through your data points.
