Comparing original cost with actual cost

Hi!

Here is a really tricky question:

Would like to compare what was originally inteded to be shipped out per month and what really is to be shipped out.

Have a cost rescource which holds the sales amount for each Project. Would now like to compare the summarized value of the sales amount using the dates from the baseline and the original plan. Note! The baseline cost and the actual cost is really the sales price and the baseline cost and actual cost holds the same amount for each Project. So the column and the chart below refers to how the actual plan has been changed compared to the baseline plan, the sales amounts are still the same, in march it was intended to ship out 200000 but the actual is to become 500000 according to the current plan.

Is this at all possible to do within Project?

Kind regards //Anders
