No there isn't... and that drives me crazy too. The closest free alternative, which doesn't actually show every point earned or lost but does show many of them, is the History plugin: https://github.com/NoahY/q2a-history
By the way, I happen to have been working for the last 3 months on a premium (non-free) plugin to show a graph of the points earned. I'm planning to release it tomorrow (awkward coincidence!).
Edit after "tomorrow": This is the link to the plugin http://www.question2answer.org/qa/36952/new-premium-plugin-pc-profile-customizer-v2-0-0
