Often we receive data in graphical form (e.g. from data sheets), but want that same data in numerical form. This can be time consuming to manually read points from a graph. This package provides a GUI to assist in this task.
One simply identifies two known x-values and two known y-values from the graph image as reference points. Then one may click on any point on the graph and the GUI will return its x and y value.
Works with linear and log scales. Also generates axes data if you want to plot other data over your image at the same scaling.
