Surprised on how little graphs one can see from the dive.

I'm really surprised how little graphs dive generates. I've always thought Garmin has a lot of data even if the data would be pretty pointless.

But from the dive you don't see things like:

N2 loading (No N2 graph)
CMS loading (No pO2 graph, no OTU graph)
Air consumption in some other unit than pressure ("SAC/RMV/ATR: Enables the transceiver to be included in volumetric surface air consumption (SAC), respiratory minute volume (RMV), and air time remaining (ATR) estimates")
The tank pressure, is not shown that the unit reads, but as adjusted to working pressure?! "Working Pressure: Sets how much pressure the tank has when full. This value is used to determine the upper end of the pressure gauge, and to calculate respiratory minute volume (RMV) for tanks using psi units."

Side-note: This working pressure is pretty badly documented and one doesn't get much smarter with searching forums https://forums.garmin.com/outdoor-recreation/outdoor-recreation/f/descent-mk2-mk2i/283360/working-pressure--significance - ok? But why the graph is done with working pressure, not the real pressure? Don't get it.

In the Dive app, one can see details like Avg SAX, Avg RMV, Avg Pressure Rate. But why no graphs? Are those so constant that there wouldn't be any sense in them? Or would they just generally match to depth graph? But what if they wouldn't match and there's something special happening, wouldn't it be nice to see from the graphs that "on this part I got scared of X and the consumption skyrocketed".

But at least now with one real dive with Garmin one understands why the Dive App exists, as it's the only one that can show these data's and like only one where one can eg. mark the weights.

you can also try to look at subsurface it support Garmin device. But i don't know how well they parse data from it.

I've transferred one dive there, seems to work a-ok, but it's not like the same thing. Garmin activities are public and I can just link to them and with subsurface it would be just for me.

Just somewhat surprised how little graphs one can get from dive, compared for example run with all the running dynamics, there's a lot of graphs those benefits are so and so, so could have guessed in dives they would also graph everything they can.

I'm pretty sure some of those appear in the activities widgit on the watch after the dive, esp nitrogen, and in the app

But you're right more graphs would be nicer, esp wrt to standardised ideals like age,height, vo2 max etc

Duplicate, see above

I found some graphs hidden in the Dive app. One needs to open the activity and then open "Dive Timeline". There's PO2, Gas Consumption graphs and the consumption one can change to be SAC, RMV or Pressure Rate.

But yeah, would be nice to get these to the GCW also as these are just for me.

In the Dive Timeline you can also click on the graph headers and it gives you a zoomed in view and you can thenadd an overlay so you can see heart rate and air consumption if you want. It's pretty nifty.

But that's still just in the Dive app. Not in GCW which was my surprise.
