  My first suggestion would not be to hard code anything. It would probably be better if you kept your chart dynamic. The example code below reads data points from an XML document and adds them to an ArrayList (.NET collection). The XML looks like the following: 0.0 0.0 5.0 10.0 10.0 15.0 15.0 20.0 20.0 25.0 The code below uses XPath expressions in conjunction with the XML framework provided by .NET XmlDocument l_doc = new XmlDocument(); l_doc.Load(@"..\..\ChartPoints.xml"); ArrayList l_listPoints = new ArrayList(); // select all Point Nodes that have ChartPoints as its parent node XmlNodeList l_listNodes = l_doc.SelectNodes("//ChartPoints/Point"); for(int l_nIndex = 0; l_nIndex < l_listNodes.Count; l_nIndex++) { XmlNode l_currentNode = l_listNodes.Item(l_nIndex); // select the x and y node associated with the current node XmlNode l_NodeX = l_currentNode.SelectSingleNode("./XVal"); XmlNode l_NodeY = l_currentNode.SelectSingleNode("./YVal"); if(l_NodeX != null && l_NodeY != null) { CDataPoint l_Point = new CDataPoint(); l_Point.m_dX = Convert.ToDouble(l_NodeX.InnerText); l_Point.m_dY = Convert.ToDouble(l_NodeY.InnerText); l_listPoints.Add(l_Point); } }
