Teachers often ask whether students have to plot straight line graphs in their individual investigation. The answer is no, This used to be the case but not anymore. This is good news since having to linearise equations seriously limits their choice of topic about half of my students this year plotted curves. It's worth noting that the equation of the curve must have been predicted in the theory, random polynomials are pointless. Thankfully LoggerPro enables custom curve fitting.

Here are selection of this year's.
