This y axis placement is quite common for stock tickers. I suppose it is intended to make it easiest to see the most up to date price, which is the pertinent information for most readers. Similarly, the y axis starting at zero is conventional wisdom for scientific data, but I suppose the most relevant visual for stocks is the price fluctuation, which is best viewed with y autoscaling over the selected timeframe.
First of all, why is the y axis on the right? Second of all, this is made look much bigger than it is as the y axis doesn’t start at 0.
