    I have a basic question about the graphs of Vega shown in most text books. Vega is defined as "the option's sensitivity to a change in the volatility of the underlying asset". But all option books I have show only the graph of Vega vs Underlying Price. I have not seen any graph of Vega vs Volatality.
    Am I missing something in the interpretation of Vega?

    Thanks for your help.
