Have you ever had data trapped in a graph with no means of accessing the sweet, juicy points yourself? The solution you need is WEBPLOTDIGITIZER:
This is a really rad web program in which you drag and drop the graph of illusive and/or aggravating properties into an interactive window, where you simply coordinate the axes and select the desired data points, or trend line to be generated into an x-y (or other coordinate system) csv file !
If you weren’t already convinced, then follow as I extract useful but obscured information from an informative graph. Barney Stinsons ‘Ewok Line’, pictured below, can be digitised and the entire data set accessed.
I now have the data that will help me reveal the age of anyone who’s feelings I know towards Ewoks with high levels of certainty! I could also use the plot to compare it to my own data set, to see the questionability of the Ewok Line theorem.
Comparing data sets it appears the Ewok Line isn’t completely robust!
