Having all lines normalized so they start from a common point at x = 0 would be helpful. That would allow reading the total returns as percentage of the initial (1987) investment and compare them. Similarly in the drawdown chart, if it starts at 1987, it makes no sense to start the dollar at -81%. If I am looking at a chart from 1987 to 2022, I want to see how the dollar did compared to other assets in that time peri…
You don't really need that on a logarithmic plot since the ratio of stock prices is always a constant vertical separation. It is very necessary on linear pricing plots.
As far as I can tell, the different intercepts just add noise (price of a single stock) that is not helpful to visualize what the plot is supposed to be showing (total returns).
