Anki add-on: Correct Answers Graph

This add-on adds a graph showing the percentage of correct answers to the statistics window. By hovering the mouse over the graph, statistics for that point in time are shown. Optionally, reviews for learning and relearning cards can be shown in one graph. This add-on does not support the new stats in Anki 2.1.28 or later. To access the old stats, hold shift while opening the stats window.
