Is my oxygen variation chart high or low? I can't tell!

I look at this chart and it looks like astronomically high variation to me... swinging way up and then going down all night long.

But then I wonder, what if the Y axis on here is shrunk and this is basically a flat line that's been exaggerated out. So I think maybe this is actually almost no variation at all.

 

Basically I have no idea the scale of this. Are there example of what a high and low variation would look like?

No idea about the scale, but as long as it stay green, that is good, i.e. low variation.  When it gets to what Fitbit considers high variation, you will see the chart turn to orange at the top of a peak.  Even then sometimes (at least it seems to me) it can be explained by waking for a few minutes to use the bathroom, typically getting higher saturation when awake and breathing more often.
