Which charts would tell me the movement of a stock is independent or related to the movement of the overall market?

What you need is a relative strength chart. A relative strength chart is simply the price of the stock divided by the market or sector index. If the line is rising, then the stock is out-performing the market or sector.

Relative strength should not be confused with the Relative Strength Index (RSI), which is a momentum oscillator.
