1、前言
最近开发一个小软件，涉及到曲线绘图，绘制多条曲线，并显示标签，以及数据点的其它信息。不想用其它增强性能的控件，还是想研究微软原始的标准绘图控件 chart。在网上查了很多资料没有这方面的详细的正确知识，要么是代码语法结构错误，要么就是虚假的张冠李戴，浪费时间。通过不懈的摸索和测试，终于找到了正解。其实很简单，只是微软网站关于控件的指导太模糊，示例代码太简单，没有详细注解。
数据为超声波测深仪和 Hypack 软件测量的输出原始数据，数据存在多面性，有平面坐标和水深关系、有时间和水深的关系，水深有常规测量和定标测量（按间距或时间差测量水深的事件）。为了展示各种关系曲线以一目了然，就涉及到绘图控件 chart 的多 Y 值应用。

4.1、绘图要求
4.1.1 绘制测区平面坐标
4.1.2 绘制时间和水深的剖面图
绘制时间和水深的剖面图，线型为折线，数据点 X 为时间，Y1 为水深（绘制在横坐标以下），并同时显示时间和定标水深的剖面图，并标注定标序号，Y2 为定标序号。
4.1.3 绘制起点距和水深的剖面图
绘制起点距和水深的剖面图，线型为折线，数据点 X 为起点距，Y1为水深（绘制在横坐标以下），并同时显示起点距和定标水深的剖面图，并标注定标序号，Y2 为定标序号。
