Eagle Tree Datalogger on the horizon for me, anything I need to know

Thats what is frustrating - I can graph the data as long as its on the V3, I can see it and I know there's amps and volts versus time which is all I've been trying to record so far. Then I name it and save it (accept the default file extension), then clear the recorder for the next run. When I come back and reload it later, I can find ihe file, but there's nothing but the time in the file, there's no volts vs time and no amps vs time data like I was displaying when I had it graphed on the screen. I am using the 10hz rate and typically only running for 4-6 min.

The other thing I've been disappointed in is trying to save the graph as a jpg. That resulted in a tiny, tiny square that had nothing in it when I blew it up. If I can't save the data some how, the potential benefit is marginalized.
