But not having enough control points that have been given, we can't accurately show the regulation of data change with the BEZIER curve.

但用BEZIER曲线显示数据变化规律时，若控制点数量不足，就难以精确反映数据的变化规律。

youdao

A quadratic bezier curve has a start and an end point (blue dots) and just one control point (red dot) while a cubic bezier curve USES two control points.

它们都有一个起点一个终点图中的蓝点，但二次方贝塞尔曲线只有一个红色控制点点而三次方贝塞尔曲线有两个。

youdao

Unlike a cubic Bezier curve, which USES two control points, a quadratic cubic Bezier curve USES a single control point.

三次贝塞尔曲线使用两个控制点，与之不同，二次贝塞尔曲线只使用一个控制点。
