少有人走的路微软的Chart图表控件好处是免费的，并且基本的画曲线、柱状图等功能还是有的。
虽然Teechart非常优秀，但是它是收费的。
所以熟悉一下Chart没什么坏处，目前勇哥有一个案子也用到了Chart，是一款测量R角的设备。
勇哥提供两段代码来演示Chart的用法，以后有机会，还是想把Chart写成一个ChartHelper类集成到netMarketing中去。
第一个演示例子：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Windows.Forms.DataVisualization.Charting;
namespace RealTimeChart
{
public partial class Form1 : Form
{
private double vm;
//private double dm;
private Queue<double> VM = new Queue<double>(1000);
// private Queue<double> DM = new Queue<double>(1000);
private bool Ready;
private bool control;
public Form1()
{
InitializeComponent();
}
public void FlyData_Line()
{
///图表区
this.chart1.ChartAreas.Clear();
ChartArea chartarea = new ChartArea("FlyData");
chart1.ChartAreas.Add(chartarea);
chartarea.AxisX.Maximum = VM.Count;
chartarea.AxisX.MajorGrid.LineColor = Color.Gray;
chartarea.AxisY.MajorGrid.LineColor = Color.LightCyan;
chartarea.AxisX.ScrollBar.Enabled = false;
///title
this.chart1.Titles.Clear();
this.chart1.Titles.Add("FlyData");
this.chart1.Titles[0].Text = "FlyData";
this.chart1.Titles[0].ForeColor = Color.Red;
this.chart1.Titles[0].Font =new System.Drawing.Font("Microsoft Sans serif", 12f);
///series
this.chart1.Series.Clear();
Series series = new Series("FlyData");
this.chart1.Series.Add(series);
series.ChartArea = "FlyData";
series.ChartType = SeriesChartType.Spline;
series.MarkerBorderWidth = 3;
series.MarkerBorderColor = Color.SkyBlue;
series.MarkerSize = 1;
series.MarkerStyle = MarkerStyle.Circle;
}
///生成随机数放入列表中
private void ChartData()
{
if(VM.Count>100)
{
VM.Dequeue();
//DM.Dequeue();
}
if (Ready)
{
VM.Enqueue(vm);
//DM.Enqueue(dm);
}
for (int i = 0; i < VM.Count; i++)
{
this.chart1.Series[0].Points.AddY(VM.ElementAt(i));
}
}
private void btnStart_Click(object sender, EventArgs e)
{
if (control == false)
{
Ready = true;
btnStart.Text = "停止";
control = true;
}
else
{
Ready = false;
btnStart.Text = "开始";
control = false;
}
}
private void Form1_Load(object sender, EventArgs e)
{
timer1.Enabled = true;
}
private void timer1_Tick(object sender, EventArgs e)
{
Random r = new Random();
vm = r.Next(0,200);
FlyData_Line();
ChartData();
}
}
