title: How to do I change a Series color in Excel using C#?
body: <p>I have written a program in C# whereby it automatically generates a graph for me from a CSV file and puts it onto a new XLS file. However, I need to change the color of the Line (as it is a Line Chart) to red rather than the default blue.</p>
  
  <p>I am finding this extremely difficult to do and the stuff I've found online has not worked. Please can someone tell me how to do this? </p>
