zedGraph绘制串口数据时出现延时和卡机

Question

zedGraph绘制串口数据时出现延时和卡机，要怎么解决。大约采集了40K左右的数据！

Answer 1

推荐你用 doworer 去做，这样 就不会死机了， 用多线程在

Answer 2

        #region 画图程序
        private void paint()
        {
            string s = "";
            LineItem mycurve;
            if (colloctdata.Count > 0)
            {
                s = colloctdata.Dequeue();
                Xray_position.Text = System.Convert.ToString(System.Convert.ToDouble(System.Convert.ToInt16(s.Substring(25, 5).Replace(" ", ""), 16))/200);
                collect_position.Text = System.Convert.ToString(System.Convert.ToDouble(System.Convert.ToInt16(s.Substring(31, 5).Replace(" ", ""), 16)) / 200);
                if (string.Equals(s.Substring(0, 11), "68 03 07 08"))
                {
                    double x = System.Convert.ToDouble(System.Convert.ToDouble(System.Convert.ToInt16(s.Substring(31, 5).Replace(" ", ""), 16)) / 200);
                    double y = System.Convert.ToDouble(System.Convert.ToInt32(s.Substring(12, 11).Replace(" ", ""), 16));
                    string showdata = '\n'+x.ToString().PadRight(7) + y.ToString().PadLeft(6)+"\n\r";
                    safeAddtrText(showdata);//显示数据的委托
                    list.Add(x, y);
                    mycurve = zedGraphControl1.GraphPane.AddCurve("", list, Color.Red, SymbolType.None);
                    mycurve.Line.IsAntiAlias = true;//设置连接线的抗锯齿效果
                    this.zedGraphControl1.GraphPane.AxisChange();
                    //this.zedGraphControl1.Invalidate();
                    this.zedGraphControl1.Refresh();
                } 
            }            
        }
        #endregion
这是我写的画图显示！
