How to create a line chart to compare trend of two activities

This video series (http://office.microsoft.com/en-us/ex...777.aspx?CTT=1 ) talks about the different steps to creating charts. Since I cannot see any attempt to create a chart (though that could have been lost on the way to viewing the file in Google Docs, since I don't have Excel on this computer), I am guessing that you are unfamiliar with any of the steps to creating charts in Excel. If that is the case, this video series should be a good place to start to understand how to select the data you want charted, how to insert charts, and a little bit of how to choose what chart type you want.
