Graphic in excel for practicum

Homework Statement

So I have to make three charts for the measurments that we made in class (physics experiments but it's not important). 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.

Homework Equations

What kan I do to fix it?

It is impossible to tell what went wrong if you don't show the graphs (and the data, if relevant).
Do you expect the data to follow an exponential/logarithmic function?

 

[alkgeo]

Yes, the last two had to be in a logarithmic\exponential trendline. Do you think the measurments were wrong to begin with?

Yes the last two had to be those, do you think the measurments were wrong to begin with?
