Question

我试图使用c＃在图表上显示Myo数据。我从Myo收到数据并将其发送到图表，但它不会显示任何内容。网上的例子对我没有帮助！这是代码（我想我有线程但不知道，生产者类从myo接收原始emg数据，Form1应该显示它）：

using MyoSharp.Communication;
using MyoSharp.Device;
using MyoSharp.Exceptions;
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 MyoThings
{
    public partial class Form1 : Form
    {
        int i = 0;

        public Form1()
        {
            InitializeComponent();
        }



        private void button1_Click(object sender, EventArgs e)
        {
            Producer producer = new Producer();
            producer.StartConnection();
        }

        public void receiveData(int data)
        {
            Console.WriteLine(data);
            chart1.Series[0].Points.Add(i++, data); // won't add anything - 
            chart1.Invalidate();

        }


    }

    class Producer
    {
        Chart chart = new Chart();

        public void StartConnection()
        {
            using (var channel = Channel.Create(ChannelDriver.Create(ChannelBridge.Create(),
                MyoErrorHandlerDriver.Create(MyoErrorHandlerBridge.Create()))))
            {
                using (var hub = Hub.Create(channel))
                {
                    hub.MyoConnected += (sender, e) =>
                    {
                        Console.WriteLine($"Myo Connected, handle: {e.Myo.Handle}");
                        e.Myo.Vibrate(VibrationType.Short);
                        e.Myo.EmgDataAcquired += Myo_EmgDataAcquired;
                        e.Myo.SetEmgStreaming(true);

                    };
                    channel.StartListening();
                    //int i = 0;
                    while (true)
                    {

                    }
                }
            }

        }

        private static void Myo_EmgDataAcquired(object sender, EmgDataEventArgs e)
        {
            //Console.WriteLine(e.EmgData.GetDataForSensor(1));
            Producer producer = new Producer();
            Form1 form = new Form1();
             //sends data of myo to chart
            form.receiveData(e.EmgData.GetDataForSensor(1));

        }
    }
}

我可以自己回答。我将图表发送到生产者类并添加了点

从Myo接收数据并在c＃图表上显示
