Charts displaying the daily price of stock REM and the Treasury 10Y Yield

Below shows the historical price of stock REM and below it show the yield of the 10-year Treasury. The price of REM is sometimes effected by interest rate changes but because these companies hedge interest rates there is no consistent pattern. Since the two do not share a Y-axis you must have two charts or use a Line and Stacked column chart which is the better chart to use.
