Hydrograph Plots

In reviewing the Hydrologic Toolbox, it occurred to me we don't have just a hydrograph plot in hyswap. Obviously, could use generic plot tools to create one, but I wonder if we want a hydrograph plot function that would be more convenient to have it styled and labeled as a hydrograph? Would be an easy function to add that would be useful for the package to be used by hydrologists.
