If you are referring to a simple RC circuit, neither the charge nor the discharge curve will change.
Both sets of values you give yield a time constant of 470 milliseconds. It takes one time constant to charge the capacitor to about 63 percent of the voltage applied or to discharge the capacitor to about 37 percent; and it takes five time constants to fully charge or discharge the capacitor.
Changing values will not affect the shapes of the charge and discharge curves:

How are you using the RC circuit? What are you trying to do?
Both curves are most nearly "linear" (but still not perfect) for the first 20 percent.
