There seems to be something wrong with your chart. The MtGox price numbers are about 10x too small, and all the other traces are smushed flat near the bottom of the chart. And I can only see two of them. Does each of them need its own vertical scale, perhaps? Also there are lots of 0, Infinity and NaN values in your data below the chart.
Oh, I totally need to update the ticker scraping code >_<
Thanks for noticing, it always breaks when I pay least attention to it.
