在套接字编程中读取数据的错误 [英] error of reading data in socket programming

问题描述

我在c＃windows应用程序上有一个图表。当鼠标放在它们上面时，我想缩放图表的每个点。喜欢谷歌地图



我的意思是我不想缩放图表的所有部分我想要缩放只是像谷歌地图一样的特殊点



代码：

I have a chart on my c# windows application. I want to zoom every point of chart when mouse on them. like google map

I mean I don't want zoom all part of chart I want zoom just specefic point like google map

code:

void CreateNewGraph()
            {
                // Create new Graph
                chart = new Graph.Chart();
    
               
                chart.Location = new System.Drawing.Point(13, 185);
    
               
                chart.Size = new System.Drawing.Size(900, 500);
    
               
                chart.ChartAreas.Add("draw");
    
                
    
                
                chart.ChartAreas["draw"].AxisX.Minimum = 0;
                chart.ChartAreas["draw"].AxisX.Maximum = 20;
    
                
                chart.ChartAreas["draw"].AxisX.Interval = 1;
    
               
                chart.ChartAreas["draw"].AxisX.MajorGrid.LineColor = Color.White;
    
                
                chart.ChartAreas["draw"].AxisX.MajorGrid.LineDashStyle = Graph.ChartDashStyle.Dash;
    
                
                chart.ChartAreas["draw"].AxisY.Minimum = -0.4;
                chart.ChartAreas["draw"].AxisY.Maximum = 1;
    
                
                chart.ChartAreas["draw"].AxisY.Interval = 0.2;
    
                
                chart.ChartAreas["draw"].AxisY.MajorGrid.LineColor = Color.White;
    
                
                chart.ChartAreas["draw"].AxisY.MajorGrid.LineDashStyle = Graph.ChartDashStyle.Dash;
    
                
                chart.ChartAreas["draw"].BackColor = Color.Black;
    
    
                
                var series = chart.Series.Add("Test");
    
                   
                chart.Series["Test"].ChartType = Graph.SeriesChartType.Line;
    
                
                chart.Series["Test"].Color = Color.Yellow;
    
               
                chart.Series["Test"].BorderWidth = 3;
    
    
                chart.Legends.Add("MyLegend");
                chart.Legends["MyLegend"].BorderColor = Color.YellowGreen;
    
                // Set automatic zooming
                chart.ChartAreas["draw"].AxisX.ScaleView.Zoomable = true;
                chart.ChartAreas["draw"].AxisY.ScaleView.Zoomable = true;
    
                // Set automatic scrolling 
                chart.ChartAreas["draw"].CursorX.AutoScroll = true;
                chart.ChartAreas["draw"].CursorY.AutoScroll = true;
    
                // Allow user selection for Zoom
                chart.ChartAreas["draw"].CursorX.IsUserSelectionEnabled = true;
                chart.ChartAreas["draw"].CursorY.IsUserSelectionEnabled = true;
    
                chart.ChartAreas["draw"].AxisX.ScaleView.Zoomable = true;
                chart.ChartAreas["draw"].AxisY.ScaleView.Zoomable = true;
    
                //chart.MouseWheel += new MouseEventHandler(chart_MouseWheel);
            }

推荐答案

我不认为.net框架的图表具有此功能。你宁愿使用复杂的图表，如devexpress的chartcontrol。

I don't think chart of .net framework has this ability. You'd rather use a sophisticated chart like chartcontrol of devexpress.
