the relationship between interest rates and time, determined by plotting the yields
of all or as many bonds
of similar credit quality (eg: Treasuries or AA - rated Corporates), against their maturities; yield curves typically slope upward since longer maturities normally have higher yields, although it can be

Search Results Scattergraph shows several smoothed yield curves for different fixed - income product

of bonds, which is significantly larger than the number
of bonds offered by Fidelity on any given day
