根据一大串 points 巧妙绘制曲线

for (int i = 0;i<size;i++) {
    Entity data = list.get(i);
    currentPosX = (i + 1) * chartSpace + i * chartWidth;
    currentPosY = getHeight() - mBottomBlankSize - (data.value() / getMaxAqiValue()) * (chartHeight) - mPaddingPopAndChart;
    if (i == 0) {
        mPath.moveTo(currentPosX, currentPosY);
        lastX = currentPosX;
        lastY = currentPosY;
    } else {
        float cX = (currentPosX + lastX) / 2;
        float cY = (currentPosY + lastY) / 2;
        mPath.quadTo(lastX, lastY, cX, cY);
        lastX = currentPosX;
        lastY = currentPosY;
    }
    mControlPoints.add(new PointF(currentPosX, currentPosY));
}

原理即把实际点作为控制点，而目标点通过计算得到
