C#根据当前进程，画图，并且展示进程消耗情况，进程数为4，存储在queue队列中，请给出具体代码

在C#中，你可以使用Windows Forms和System.Diagnostics命名空间来监控进程并实时绘制图形。这里是一个简单的示例，它会创建一个窗体，显示四个进程的CPU使用率，使用Queue存储进程信息：

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Windows.Forms.DataVisualization.Charting;

public partial class MainForm : Form
{
    private List<double> cpuUsage = new List<double>();
    private Queue<ProcessInfo> processQueue = new Queue<ProcessInfo>();
    private Chart chart1;

    public MainForm()
    {
        InitializeComponent();
        chart1 = new Chart();
        chart1.ChartAreas.Add(new ChartArea());
        this.Controls.Add(chart1);
    }

    private void UpdateChart()
    {
        while (processQueue.Count > 0)
        {
            ProcessInfo pInfo = processQueue.Dequeue();
            double cpuPercent = pInfo.CpuPercentage;
            cpuUsage.Add(cpuPercent);
            cpuUsage.RemoveAt(0); // Remove oldest data if queue is full

            Series series = chart1.Series["Series1"];
            series.Points.AddXY(pInfo.ProcessName, cpuPercent);

            // Update UI
            chart1.Invalidate();
        }
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        // Get processes from the system
        foreach (Process p in Process.GetProcesses())
        {
            // Assuming ProcessInfo is a custom class with properties like ProcessName and CpuPercentage
            ProcessInfo pInfo = new ProcessInfo { ProcessName = p.ProcessName, CpuPercentage = p.TotalProcessorTime.TotalMilliseconds / p.Id };
            processQueue.Enqueue(pInfo);

            // Limit to 4 processes for simplicity
            if (processQueue.Count >= 4) break;
        }

        // Update chart every tick
        UpdateChart();
    }

    public class ProcessInfo
    {
        public string ProcessName { get; set; }
        public double CpuPercentage { get; set; }
    }
}

// In your form constructor or somewhere else, start the timer
MainForm mainForm = new MainForm();
mainForm.timer1.Interval = 1000; // 1 second interval
mainForm.timer1.Start();

// Make sure you have a button or some trigger to add new processes manually, if needed
private void addButton_Click(object sender, EventArgs e)
{
    ProcessInfo pInfo = // Create ProcessInfo object manually
    mainForm.processQueue.Enqueue(pInfo);
}

这个例子假设`ProcessInfo`类存在并且包含`ProcessName`和`CpuPercentage`属性。`timer1_Tick`事件会在每秒触发一次，获取系统中的进程并将它们添加到队列中。同时，更新图表以显示每个进程的CPU使用情况。

注意：实际应用中，你需要处理线程同步和异常处理等问题。
