Give me perspective!

It's frustrating that stock chart graphs make it clear when a stock went up and when it went down, but not by how much. If the line goes down to the bottom of the graph, it might be alright (the opening bell just rang, and it's down .01%), or it might be horrific (the company went bankrupt).

Why not have a convention of showing not only the opening-value as a line, but the opening-value +/- mean volatility as lines of different colors. Show me the equator, plus the tropics of cancer and capricorn!
