坐标曲线在各种统计图中应该算比较难画的，主要是很难将坐标值与图中的位置对应起来.本文给出了坐标曲线的编程实现-Coordinate curve in a variety of charts that should be regarded as relatively difficult to draw, mainly it is difficult to value and map coordinates of the location of the corresponding up. In th

在金属导体中 ,电流跟电压成正比 ,伏安特性曲线是通过坐标原点的直线 ,具有这种伏安特性的电学元件叫做线性元件。-In metal conductors, the current with the voltage proportional to the volt-ampere characteristic curve is a straight line through the origin, with the volt-ampere characteristic of this electri

根据空间任意点数坐标拟合得到空间样条曲线，特别适合测量实际孔轴线拟合。-According to the spatial coordinates of any point of space-spline curve fitting, especially suitable for measuring the actual hole axis fitting.
