Chart Control in Visual Studio 2010 (Web and Windows Explained)

i have one problem.every time series add datapoints but requriement not adding datapoint on series. if (dt.Rows.Count > 0) { for (int i = 1; i < dt.Columns.Count; i++) { for (int j = 0; j < dt.Rows.Count; j++) { // Series series = new Series(); if (chart1.Series.Where(x => x.Name == dt.Rows[j][i].ToString()).Count() > 0) { } else { Series series = new Series(dt.Rows[j][i].ToString()); //series.Name = " "; foreach (Series seriess in chart1.Series) { if (dt.Rows[i][i].ToString() == seriess.Name) { seriess.Points.AddXY(Convert.ToDateTime(dt.Rows[j][0]).ToString(), Convert.ToDouble(dt.Rows[j][i])); } //chart1.Series.Add(seriess); } chart1.Series.Add(series); chart1.Series[i].ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Line; //chart1.Series[i].XValueMember = "DateTime"; //chart1.Series[i].YValueMembers = chanelselected; } } }

I am trying to use a network path for the images as I have a WebFarm which is loadBalanced using CISCO ACE appliance. The reason I am using a network shared folder is that at times the Chart does not show the PNG images. The problem with displaying the PNG images in the Web Farm comes when I had initially the web.config setting as shown below. <add key="ChartImageHandler" value="storage=file;timeout=10;dir=c:\TempImageFiles\;" /> So I used the network Shared path as per (blogs.msdn.com/.../managing-chart-generated-images-with-chart-image-handler.aspx) , where I have FULL Permissions on EVERYONE, NETWORK Service. Below is my current setting for the Network shared folder path and I keep getting this error: Invalid temp directory in chart handler configuration <add key="ChartImageHandler" value="storage=file;timeout=10;dir=\\servername\TempImageFiles\;" /> Can someone help. Rgds,

i will try today ...
