The graph is a bit odd on desktop too. The baseline is Feb 1, 2020, which equals 100 units on the y-axis. Given this normalization, I am less concerned about the y-axis starting at 60.

However, the graph would be much more informative if there were 10 or 20 years of data. It's unclear to me why Feb 1, 2020 is a good baseline to use.

This is an index with base 100.

The y index is very misleading, from people who should know better

Yes, but the peak is 3x the index prior to the bubble and now.
