A flexible charting library for .NET -- 非常好用的图表库(二)

   之前的成果:

  

添加了一些代码修改图表的一些属性:

 

              //改变标题颜色

            myPane.Title.FontSpec.FontColor = Color.Blue;

            myPane.XAxis.Title.FontSpec.FontColor = Color.Green;

            myPane.YAxis.Title.FontSpec.FontColor = Color.Indigo;       

//添加灰色网格线

            myPane.XAxis.MajorGrid.IsVisible = true;

            myPane.YAxis.MajorGrid.IsVisible = true;

            myPane.XAxis.MajorGrid.Color = Color.LightGray;

            myPane.YAxis.MajorGrid.Color = Color.LightGray;

            myPane.XAxis.MinorGrid.IsVisible = true;

            myPane.XAxis.MinorGrid.Color = Color.RosyBrown;

//改变图标的位置

            myPane.Legend.Position = LegendPos.Bottom;

//添加一条星状的淡绿色的曲线

            LineItem myCruve3 = myPane.AddCurve("BMW", list3, Color.PaleGreen, SymbolType.Star);

            //改变曲线的粗细

            myCurve.Line.Width = 3.1F;

            myCurve2.Line.Width = 0.2F;

            myCruve3.Line.Width = 2.5F;

            //填满第一条曲线正文的面积,由白到红渐变

            myCurve.Line.Fill = new Fill(Color.White, Color.Red, 45F);

 

            //加大symbol的大小,并用白色填充

            myCurve.Symbol.Size = 8.0F;

            myCurve.Symbol.Fill = new Fill(Color.White);

 

            //添加背景色,由白色到黄色渐变

            myPane.Chart.Fill = new Fill(Color.White, Color.FromArgb(255, 255, 210), -45);

           

            //添加标题说明和箭头

            TextObj myText = new TextObj("Interesting/nPoint", 230F, 70F);

            myText.FontSpec.FontColor = Color.Red;

            myText.Location.AlignH = AlignH.Center;

            myText.Location.AlignV = AlignV.Top;

            myPane.GraphObjList.Add(myText);

            ArrowObj myArrow = new ArrowObj(Color.Red, 12F, 230F, 70F, 280F, 55F);

            myPane.GraphObjList.Add(myArrow);
