Nitrogen and carbon dioxide on this atmospheric composition graph mirror each other and confuse me on what it actually is visually. Perhaps a filled-in graph, with vertically largest to smallest, and maybe an extra piece of info under time info on the graph showing atmospheric mass (and mass for each gas on each dot)

Image on next slide for visualization of a patch atmospheric composition I made a little while ago (without mention of atmospheric mass since I do not have that information in the game)
