提高MSChart工具的性能？

改善MSChart工具的性能？提高MSChart工具的性能？

我們在一個ASP.net 3.5 web應用程序上使用MSChart，並注意到啓用工具提示時顯着的緩慢。繪製圖表的表現非常緩慢。由於我使用大型數據集繪製圖形，圖表輸出爲JPEG，並且總共包含500多個數據點。

  chart.DataSource = dv; 
      chart.Series.Invalidate(); 
      chart.Series.SuspendUpdates(); 

      chart.Series["Series1"].XValueMember = "Time_Value"; 
      chart.Series["Series1"].YValueMembers = "Total1"; 
      chart.Series["Series2"].XValueMember = "Time_Value"; 
      chart.Series["Series2"].YValueMembers = "Total_thru"; 
      chart.Series["Series3"].XValueMember = "Time_Value"; 
      chart.Series["Series3"].YValueMembers = "Total2"; 
      chart.Series["Series4"].XValueMember = "Time_Value"; 
      chart.Series["Series4"].YValueMembers = "Total2_thruput"; 
      chart.Series["Series5"].XValueMember = "Time_Value"; 
      chart.Series["Series5"].YValueMembers = "BAWA_Total"; 
      chart.Series["Series5"].LegendText = "Count"; 
      chart.Series["Series5"].IsVisibleInLegend = true; 
      chart.DataBind(); 

      chart.Series["Series2"].LegendText = "Throughput1"; 
      chart.Series["Series2"].IsVisibleInLegend = true; 
      chart.Series["Series1"].LegendText = "Count1"; 
      chart.Series["Series1"].IsVisibleInLegend = true; 
      chart.Series["Series3"].LegendText = "Count2"; 
      chart.Series["Series3"].IsVisibleInLegend = true; 
      chart.Series["Series4"].LegendText = "Throughput2"; 
      chart.Series["Series4"].IsVisibleInLegend = true; 

      chart.ChartAreas[0].AxisX.LabelStyle.Angle = -90; 
      chart.ChartAreas[0].AxisX.LabelStyle.Font = new System.Drawing.Font("Trebuchet MS", 6.00F, System.Drawing.FontStyle.Bold); 
      chart.ChartAreas[0].AxisX.Interval = 600; 
      chart.ChartAreas[0].AxisX.IsStartedFromZero = true; 
      chart.ChartAreas[0].AxisX.TitleFont = new System.Drawing.Font("Trebuchet MS", 10.00F, System.Drawing.FontStyle.Bold); 
      chart.ChartAreas[0].AxisY.TitleFont = new System.Drawing.Font("Trebuchet MS", 10.00F, System.Drawing.FontStyle.Bold); 
      chart.ChartAreas[0].AxisY2.TitleFont = new System.Drawing.Font("Trebuchet MS", 10.00F, System.Drawing.FontStyle.Bold); 

      chart.Legends[0].Docking = Docking.Bottom; 
      chart.Legends[0].IsDockedInsideChartArea = false; 
      chart.Legends[0].TableStyle = LegendTableStyle.Wide; 
      chart.Legends[0].Alignment = StringAlignment.Center; 
      chart.Series[0].ToolTip = "#VALY{d} (#VALX)"; 
      chart.Series[1].ToolTip = "#VALY{d} (#VALX)"; 
      chart.Series[2].ToolTip = "#VALY{d} (#VALX)"; 
      chart.Series[3].ToolTip = "#VALY{d} (#VALX)"; 
      chart.Series[4].ToolTip = "#VALY{d} (#VALX)";

您還沒有顯示工具提示的代碼。工具提示也可以顯示一個常量字符串。你的意思是在工具提示中顯示DataPoint的值嗎？這個系列的chart.Series["Series5"].XValueMember = "Time_Value";是什麼？其YValueMember未設置。除了這個問題還不清楚，你能解釋一下嗎？

我正在從數據庫中取值，並綁定到系列和工具提示。 – Amirtha
