Chart控件

Chart控件是微软自带的一种图形可视化组件，使用简单灵活。在.NET4.0之后（即VS2010之后）已集成在了VS里面，直接拖拽控件到窗体即可使用。
需要使用命名空间：using System.Windows.Forms.DataVisualization.Charting;
主要包含如下集合

Chart
- ChartAreas
- Series
- Titles
- Legends
- Annotations

Chart属性详述

Chart属性设置

图表样式属性

元素渐变样式：Chart1.BackGradientStyle=System.Windows.Forms.DataVisualization.Charting.GradientStyle.TopBottom;

边框外观样式：Chart1.BorderSkin.SkinStyle=System.Windows.Forms.DataVisualization.Charting.BorderSkinStyle.Emboss;
图表背景颜色：Chart1.BackColor = System.Drawing.Color.Yellow;

数据样式属性

X轴的数据源: Chart1.Series[“Series1”].XValueMember = “name”;
Y轴的数据源: Chart1.Series[“Series1”].YValueMembers = “mobile”;
设置颜色: Chart1.Series[“Series1”].Color = System.Drawing.Color.Red;
图表类型:Chart1.Series[“Series2”].ChartType=System.Web.UI.DataVisualization.Charting.SeriesChartType.Line;

Chart控件鼠标滚轮事件特殊处理

 // 滚轮事件
 private void chart1_MouseWheel(object sender, MouseEventArgs e)
 {            
     Console.WriteLine("e.Delta:" + e.Delta);
     if (e.Delta > 0)//鼠标向上
     {
         if (chart1.ChartAreas["ChartArea1"].AxisX.ScaleView.Size < 100)//判断显示的最大数值
             chart1.ChartAreas["ChartArea1"].AxisX.ScaleView.Size += 5;//+=5---滚动一次显示5个
     }
     else//鼠标向下滚动
     {
         if (chart1.ChartAreas["ChartArea1"].AxisX.ScaleView.Size > 1)
             chart1.ChartAreas["ChartArea1"].AxisX.ScaleView.Size -= 5;// - = 5---滚动一次减小显示5个               
     }
 }

 private void chart1_MouseEnter(object sender, EventArgs e) // 当鼠标移动到控件上-触发事件
 {
     Console.WriteLine("Mouse Enter");
     MouseWheel += new MouseEventHandler(chart1_MouseWheel); // 调用滚轮事件
 }

Series绑定数据

int[] c = new int[100];
for (int i = 0; i < 100; i++)
{
    c[i] = 1;
    chart1.Series["Series1"].Points.DataBindY(c);//c的数据给Y，X=100
    // chart1.Series["Series1"].Points.DataBind(c);
    // chart1.Series["Series1"].Points.DataBindXY(c);
    // chart1.Series["Series1"].Points.DataBindY(c);
}
