Physics practicum working with excel

[alkgeo]

So I have to make three charts for the measurments that we made in class. The first one had to be with a linear trendline, the second one with a exponential and the third one with a logarithmic trendline. For some reason the last two trendlines don't follow the dots from the measurements. What can I do to fix that?
