Creating Line Chart From Data

Hi,

I'm sure you Excel whizzes can help me in this matter. I have created a spreadsheet which I use to track football (soccer) predictions for a little competition between friends. What I would like to do is create a line chart showing each participants cumulative score.

I've attached the spreadsheet for you to look at. What I would like is to have the date (column B) on the X axis as a unique value. The Y axis to be the points accumulated scale and for each player to be shown on the chart with the cumulative points gained throughout the season. For example, Sunny's Superstars to have 0 points on Tuesday, 9 November 2010, 5 points on Wednesday, 10 November 2010 then 9 points on Saturday, 13 November 2010 (as it's a cumulative total going forward). The points for each player are shown under the cell "pts". Can this be done directly from the data or do I need to use formulas to set up the data?
