利用ComponentOne生成柱状图和折线图相结合

利用ComponentOne生成柱状图和折线图相结合，ComponentOne这个我就不用介绍了，大家搜一下就知道了。

可以直接在窗体上面把两个相结合起来。也可以完全通过代码来实现。以下就是通过代码来实现的：

先拖放一个C1Chart到窗体上面。然后删除上面的折线图：

删除后效果如下：

Designer.cs文件：

private void InitializeComponent()
{
System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(Form4));
this.c1Chart1 = new C1.Win.C1Chart.C1Chart();
((System.ComponentModel.ISupportInitialize)(this.c1Chart1)).BeginInit();
this.SuspendLayout();
// 
// c1Chart1
// 
this.c1Chart1.Location = new System.Drawing.Point(28, 33);
this.c1Chart1.Name = "c1Chart1";
this.c1Chart1.PropBag = resources.GetString("c1Chart1.PropBag");
this.c1Chart1.Size = new System.Drawing.Size(427, 303);
this.c1Chart1.TabIndex = 0;
// 
// Form2
// 
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(467, 434);
this.Controls.Add(this.c1Chart1);
this.MinimumSize = new System.Drawing.Size(475, 462);
this.Name = "Form2";
this.Text = "Separate Group Visual Effects";
this.Load += new System.EventHandler(this.Form1_Load);
((System.ComponentModel.ISupportInitialize)(this.c1Chart1)).EndInit();
this.ResumeLayout(false);
}

private C1.Win.C1Chart.C1Chart c1Chart1;

后台代码：

   private void Form1_Load(object sender, EventArgs e)
        {
   //Y,Y2设置
   Area a = c1Chart1.ChartArea;
   a.AxisX.UnitMajor = 10;
   a.AxisX.UnitMinor = 10;
   //设置轴线的最大值和最小值(当AutoMin和AutoMax被设置为False时).关于此的更多信息,请参见轴线边界(209页). 
   a.AxisY.Max = 50;
   a.AxisY.Min = 0;
   //设置主要和次要刻度线之间的间距(当AutoMajor和AutoMinor属性被设置为False时). 66page
   a.AxisY.UnitMajor = 10;
   a.AxisY.UnitMinor = 10;
   // Clear 轴线标签的名
   a.AxisY.Text = "";
   a.AxisY2.Min = 0;
   a.AxisY2.Max = 100;
   a.AxisY2.UnitMajor = 10;
   a.AxisY2.UnitMinor = 10;
   // Clear 轴线标签的名
   a.AxisY2.Text = "";

   ChartGroup cgroup = c1Chart1.ChartGroups.Group0;
   cgroup.ChartType = Chart2DTypeEnum.XYPlot;
   //input the data through the series collection 
   ChartDataSeriesCollection cdsc = cgroup.ChartData.SeriesList;
   cdsc.Clear(); //remove default data 
   //create the series object from the collection and add data 
   ChartDataSeries cds = cdsc.AddNewSeries();

   // Add Data for ChartGroup0, Bar chart 
   string[] MonthNames = { "10月", "11月", "12月", "13月", "14月" };
   double[] AvgPrecip = { 16, 19, 19, 19, 26 };
   //create a label for the Bar chart data series 
   cds.Label = "左軸:月降水量(㎜/h)";
   cds.FillStyle.Color1 = Color.Red;
   cds.SymbolStyle.Shape = SymbolShapeEnum.None;
   ////Use the CopyDataIn method of the ChartDataArray object to copy the X and Y value data into the data series 
   cds.X.CopyDataIn(MonthNames);
   cds.Y.CopyDataIn(AvgPrecip);
   
   ////create and add the data for the XY chart in Group1 
   ChartGroup cgroup2 = c1Chart1.ChartGroups.Group1;
   cgroup2.ChartType = Chart2DTypeEnum.Bar;

   //input the bar chart data of group1 through the series collection 
   ChartDataSeriesCollection cdsc2 = cgroup2.ChartData.SeriesList;

   //create the series object from the second collection and add data 
   ChartDataSeries cds2 = cdsc2.AddNewSeries();
   cds2.X.CopyDataIn(MonthNames);
   cds2.Y.CopyDataIn(new double[] {41, 10, 0, 0, 27 });

   cds2.Label = "右軸:月積算降水量(㎜)";
   cds2.FillStyle.Color1 = Color.Blue;
   //取得或设定轴是通常的或者反转的（升序或者降序).198page
   c1Chart1.Legend.Reversed = true;
   
  }

效果如下：

上面的写法会造成左右轴数据在条形状和折线图中显示的数据不对。改成下面的方法。

private void Form1_Load(object sender, EventArgs e)
        {
            string[] MonthNames = { "10时", "11时", "12时", "13时", "14时" };

            ChartGroup cgroup0 = c1Chart1.ChartGroups.Group0;
            cgroup0.ChartType = Chart2DTypeEnum.XYPlot;
            ChartDataSeriesCollection cdsc = cgroup0.ChartData.SeriesList;
            cdsc.Clear();
            ChartDataSeries cds = cdsc.AddNewSeries();
            cds.X.CopyDataIn(MonthNames);
            cds.Y.CopyDataIn(new double[] { 50, 30, 10, 40, 20 });

            ChartGroup cgroup2 = c1Chart1.ChartGroups.Group1;
            cgroup2.ChartType = Chart2DTypeEnum.Bar;
            ChartDataSeriesCollection cdsc2 = cgroup2.ChartData.SeriesList;
            cdsc2.Clear();
            ChartDataSeries cds2 = cdsc2.AddNewSeries();
            cds2.X.CopyDataIn(MonthNames);
            cds2.Y.CopyDataIn(new double[] { 40, 42, 40, 45, 10 });

            this.c1Chart1.ChartArea.AxisY.Min = 0;
            this.c1Chart1.ChartArea.AxisY.Max = 100;
            this.c1Chart1.ChartArea.AxisY2.Min = 0;
            this.c1Chart1.ChartArea.AxisY2.Max = 50;

            c1Chart1.ChartArea.AxisY.Compass = C1.Win.C1Chart.CompassEnum.East;
            c1Chart1.ChartArea.AxisY2.Compass = C1.Win.C1Chart.CompassEnum.West;
        }
