Drawing path by Bezier curves

I have a task - draw smooth curve

input: set of points (they added in realtime)

current solution: I use each 4 points to draw qubic Bezier curve (1 - strart, 2 and 3rd - control points, 4- end). End point of each curve is s开发者_StackOverflow社区tart point for the next one.

problem: at the curves connection I often have "fracture" (angle)

Can you tell me, how to connect my points more smooth?

Thanks!
