I want to compare own data with data generated by google analytics. For example I want to see the number of my twitter followers compared with my page visitors per day.
For a high-level overview, you could use SWIX - I haven't tried it, but it allows you to make dashboards with input from a bunch of pre-generated sources, including Twitter, Facebook & GA. I suspect that you could build something similar with YouCalc as well, but it should work out of the box with SWIX.
