They might be cheating. There appears to be a field with the total air 
consumption. DataTrak might be using that to interpolate the air 
consumption during the dive and generate a fake graph.

Suunto does this too for their older models (the vyper family). It's 
very confusing for users. They assume the graph is generated from real 
data, and wonder why libdivecomputer based applications don't show it. 
This is actually one of the most common question I receive.

The libdivecomputer api does support begin/end tank pressure. I assume 
that the Aladin's total air consumption value is the difference between 
the end and begin pressure. Unfortunately that's not enough info for 
libdivecomputer.
