Hello, I think that the underlying principle "Everything is an expression" in Mathematica is great and is one of the most exciting advantages of the Mathematica system. But it is disappointing that this principle is still fails even on such basic example as representation of a simple Plot. Consider the following: g = Plot[Sin[x], {x, 0.2, 10}] Show[FullGraphics[g], AspectRatio -> 1/GoldenRatio] It is clear that the two generated images are significantly different. This means that the function FullGraphics[] does not gives the true expression-representation of the first plot. Is it true that in really we can not get the true representation of the plot as an expression? And the principle mentioned really fails even on this? Or there is another way to get it? Thank you for your attention a priori.
