I am trying to build me a better trade log than just writing down my trades. I just upgraded to windows 7 ultimate with excel 2010. I want to make pie charts and bar charts. Bar charts to see where I am better long or short. I want to use a pie chart to see what currencies I am most profitable with. The problem I am having is when I set up the charts let say I short AUD/USD now and I do it again in a week. It shows up as 2 different bars or pieces of the pie where as I want them to calculate together on the charts. I hope someone understands what I am trying to say any help here would be great.
