[Closed] MS & Curves

I have some questions about the curve controls.

First, how can I get the values of my curve between the points.( the red part on the picture below).

Is it possible to get the same kind of curves like in blue on the same picture?

About the first question, I tried the getValue ccCurve <time_value> <float_x> method, but i don’t understand the float_x value and the result.
