So, I posted a question as to why the y-axis didn't auto adjust based upon the price history. (see discussions under my username). Turns out that when I inspected the price history, although the actual price was correct, the "high" and "low" columns had values that were way too high. After manually clearing out the "high" and "low" columns, the chart adjusted accordingly. (The "volume" column had values but did not affect the chart. For accuracy, I deleted those values as well.
