Growth of $10K (growth of a hypothetical $10,000 investment) is a chart that is commonly-used to illustrate this. Your chart would then have VFINX, VBMFX, and USDOLLAR start with $10,000 on 1987-08-03 and go from there.
It could instead show how much back at the start date one would need for it to be todays $10k? Not sure. Maybe absulute dolar values should just be ommited and work only off percentages.
