I added a second white group to generate a “CALIBRATE” data set, to make sure I know the first value applies to straight ahead which will always appear as up and that sections of the graph (view directions) are clockwise from there.

There is a Value List / Stream Filter switch (blue group) to choose either data set or potentially a third set, your real data.
