It would be very useful to add the option “average” to graphs representing
sagittal and meridional values.
It is particularly useful in 2D and 3D graphs, as it makes comparing
different lenses much easier.
lensrentals used to make such graphs: https://www.lensrentals.com/blog/2015/07/24-70-f2-8-zoom-mtf-and-variation/
These graphs are “totally” averaged, as they represent averaged values from
many tested lenses. They were published on the-digital-picture website, but
unfortunately, just like MTF variation graphs, they are no longer available.
In Imatest 3D plots and DxO 2D graphs sagittal and meridional values are
also averaged.
Adding “average“ option to Lens profile MTF plots would also be useful.
Sagittal and meridional values are perfect for detailed analysis but
average values are much better for comparing image quality of different
lenses across the frame.

That's actually not a bad idea. Should be straightforward to implement for the 2D/3D plots. I can also see what this will look like with the lens profile since it will probably increase the variance at a give distance.
I'll add it to my backlog.
