Datathief Tutorial to get data values from graphs and plots

This is a tutorial from a Biophysics class, on how to extract data values from graphs and plots. It uses as an example some trajectories of random walking particles, which was part of a homework assignment. Using DataThief, you can click on data and download the coordinates. Very helpful for published plots where the data has not been provided in a Supplementary Materials table, for example.

It does not work for log data although I set the axis on log log
