Hello Wes,
I also wanted to visualize accelerometer data and found that there was no easy way. So ended up writing a simple tool that plots accelerometer data. I have written general version of this tool and it is available for download here

If you want code to modify it for your use, let me know I will open source it. So far no one as has asked for it and I have not yet taken the trouble to setup a independent project and open source it. The tool is written in Visual Basic using Visual Studio 2010 Express.
Comments and suggestions for new features are always welcome.
Cheers
