C# Winform编程（10）Chart图表控件

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);
}
