Question

very new to C# and haven't worked with xml much so be gentle with me! I have a aspx page (C#) which draws chart data to a page and spits out an image (outputstream). At present the chart data is hard coded array(x,y) just for dev purposes. What I want to achieve is to have the y values read from a txt or xml file. The x will always be hard coded and have a total of 21 in the index. However at any given time there may be <= 21 values for the Y value. I'll want the chart to stop "plotting" once it reaches a null value for Y. So in a nutshell I need to research/achieve reading xml values into a C# array and How to code.... for i = 1 to FirstInstanceOfNull in Y (so to speak) plot the chart Jay
