I found a bunch of partial graphs.
For interior: src
For surface: src
The closest thing I could find that would cover more than innermost piece of corona is for sigma binaries. As if solar corona outer reaches were a taboo not to be spoken of, the graphs for it are always cut off way before its peak, never mind fade region. src
(of course I'm also getting temperature graphs up to Pluto distance...)
Does anyone have a single complete graph that shows temperature of the Sun from the very middle, to somewhere far out in the corona? One that would show where the peaks appear relative to each other, what size are the regions of temperature to each other - not a tiny slice but a more general image?
