Hi Shane,
I have taken a quick look at the code, but have been unable to run it as some of the subvi's are missing. It might be worth zipping up all the VIs included in the program so that these can be populated in the main VI and posting it again.
When you say the data isn't logged to the graph properly, what exactly do you mean? How do expect it to be seen, and what are you actually seeing? If you could let me know, and I'll have a look and we can go from there.
