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。

• 倾心奉献展示源代码，请不要吝啬点赞和收藏！！！

2、声明标准绘图控件 chart 命名空间

using System.Windows.Forms.DataVisualization.Charting;

3、使用绘图控件 chart

3.1、在窗体中拖入绘图控件 chart ，拖入绘图控件 chart 最简单实用。

3.2、在语句中声明加入，但要将 控件和其组件加入窗体或其它容器很麻烦，不如使用上面拖入使用。

Chart chart = new Chart();
this.Controls.Add(this.chart);

4、使用标准绘图控件 chart 绘制多曲线，应用多 Y 值在标签中显示数据其它属性

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。

4.2、绘图控件 chart 剖面图的代码实现

4.2.1、获取图幅范围大小等必要参数

double MaxWaterDepth = 0; double MaxDistance = 0; double MinDistance = 1000000;MaxSecond = 0; MinSecond = 1000000;for (int i = 0; i < POS.GetLength(0); i++){double Second = POS[i, 0];double X = Common.Round46(POS[i, 4]);double Y = Common.Round46(POS[i, 5]);POSWaterDepth[i] = Convert.ToDouble(Common.Round46(POS[i, 6], "H"));double POSPointDistance = Distance(StartDotCoordEast, StartDotCoordNorth, X, Y);//点距到点距double MeasureLine = DegreesToRadian(AzimuthCalc(StartDotCoordEast, StartDotCoordNorth, X, Y));//测线方位角double POSOnlineDistance = Cos(MeasureLine - PlannedLineAzimuth) * POSPointDistance;//在线距MaxWaterDepth = Max(MaxWaterDepth, POSWaterDepth[i]);//最大水深MaxDistance = Max(MaxDistance, POSOnlineDistance);//最大在线距离MinDistance = Min(MinDistance, POSOnlineDistance);//最小在线距离MaxSecond = Max(MaxSecond, Second);//最大秒数MinSecond = Min(MinSecond, Second);//最小秒数}double Xwide = Math.Abs(EndDotCoordEast - StartDotCoordEast);//X宽double Ywide = Math.Abs(EndDotCoordNorth - StartDotCoordNorth);//Y宽double Xcenter = (StartDotCoordEast + EndDotCoordEast) / 2;//X中心double Ycenter = (StartDotCoordNorth + EndDotCoordNorth) / 2;//Y中心double XYwideMax = Math.Max(Xwide, Ywide);//最大图幅XY宽double Inter = Math.Pow(10, ((int)XYwideMax).ToString().Length - 1);//图幅位数,坐标间隔XMin = Math.Round((Xcenter - XYwideMax / 2) / 10, 0) * 10 - 50;YMin = Math.Round((Ycenter - XYwideMax / 2) / 10, 0) * 10 - 50;XMax = Math.Round((Xcenter + XYwideMax / 2) / 10, 0) * 10 + 50;YMax = Math.Round((Ycenter + XYwideMax / 2) / 10, 0) * 10 + 50;

4.2.2、初始化绘图控件 chart
