使用ZedGraph记录（原创）

我在vs2003中，要画股票K线图以及饼图

在网上找了半天，终于确定一个工具……ZedGraph

 先在添加引用，选择ZedGraph.dll

然后在工具箱中添加ZedGraph控件

将控件拖到页面上

然后在控件的RenderGraph事件中插入代码

饼图代码：

 

 

  

Code
                        GraphPane myPane =  (GraphPane)pane[0];
            DataTable dt = ssih.GetList("1=1 order by 表A desc");
            double tag1 = 0;//看长
            double tag2= 0;//看中
            double tag3= 0;//看多
            int j=0;
            foreach(DataRow dr in dt.Rows)
            {
                if(j==0)
                {
                    tag1 = Convert.ToDouble(dr["看长"].ToString())*100;
                    tag2 = Convert.ToDouble(dr["看中"].ToString())*100;
                    tag3 = Convert.ToDouble(dr["看多"].ToString())*100;
                }
                j++;
            }
                        //标题粗体
            myPane.Title.FontSpec.IsItalic = true;
                        //背景
            myPane.Fill = new Fill( Color.White, Color.White, 45.0f );
            myPane.Chart.Fill.Type = FillType.None;
                        //说明文字位置定义
//            myPane.Legend.Position = LegendPos.Float;
            myPane.Legend.Location = new Location( 0.5f, 0.6f, CoordType.PaneFraction,
                AlignH.Right, AlignV.Top );
            myPane.Legend.IsVisible = false;
            myPane.Legend.FontSpec.Size =25f;
            myPane.Legend.IsHStack = false;
//            PieItem segment1 = myPane.AddPieSlice( tag1, Color.Red, Color.White, 45.0f, 0, "看多" +tag1.ToString("0.##")+"%" );
//            PieItem segment3 = myPane.AddPieSlice( tag2, Color.White, Color.White, 45.0f, 0, "看平" +tag2.ToString("0.##")+"%" );
//            PieItem segment4 = myPane.AddPieSlice( tag3, Color.Blue, Color.White, 45.0f,  0, "看空" +tag3.ToString("0.##")+"%" );

 

 

 

折线图及股票上证指数的K线图

 

Code
                        //上证指数k线图
            DataTable dt = ssih.GetList("1=1 order by dataDate asc");
            double[] x = new double[dt.Rows.Count +1];
            double[] y1 = new double[dt.Rows.Count +1];
            double[] y2 = new double[dt.Rows.Count +1];
            PointPairList pp1 = new PointPairList();
        
            int minCount = Convert.ToInt32( dt.Rows.Count - 80);
            
            for(int m=0;m<minCount;m++)
            {
                dt.Rows.Remove(dt.Rows[0]);
            }


            int i = 0;
            foreach(DataRow dr in dt.Rows)
            {
                y1[i] = Convert.ToDouble(dr["dxyc1"].ToString())*100;
                x[i] =new XDate(Convert.ToDateTime(dr["dataDate"]));
                pp1.Add(x[i],y1[i]);
                i++;
            }

            GraphPane myPane = (GraphPane)pane[0];
            myPane.XAxis.Type = AxisType.Date;
            myPane.XAxis.Scale.Format = "MM-dd";
            myPane.Legend.FontSpec.Size =18f;
            myPane.XAxis.Type = AxisType.DateAsOrdinal;
            myPane.Legend.Position = LegendPos.InsideTopRight;
            myPane.Legend.Location = new Location( 0.5f, 0.6f, CoordType.PaneFraction,
                AlignH.Right, AlignV.Top );
            LineItem myCurve1 = myPane.AddCurve("看多",pp1, Color.Red, SymbolType.Diamond);
        
            myPane.AxisChange();
