    You should use Path.quadTo with only one Path. If you are already doing this then I suggest increasing the number of points on the graph.

    Move to the beginning of the Path:

    Path.moveTo(x, y)

    in the middle:

    Path.quadTo(lastX, lastY, (x + lastX)/2, (y + lastY)/2)

    and at the end:

    Path.lineTo(x, y)
