This already helped me a little bit, but I'm still stuck with comparing the performance on a relative basis like its possible at Google Finance.
I somehow need to have a javascript that formats two (or more) datasets so that I can compare their performances and I have absolutely no idea how I could do this. Since Google already does this on Google Finance I thought there might be an "easy" solution. Sorry, but I'm a bit of a noob when it comes to the chart api and javascript.
