Rolling 10 year net summary of value

[Anonymous]

Trying my best to explain this:

I have a financial value in column B that's either a epxense or income (column C) ranging from 2012 to 2033. 

What I want to do is have a rolling summary of net value (income - expense) by 10 years as their own "category" for lack of better word. To visualise in both a table/matrix and linechart

example: (multiple projects for each year, with both incomes and costs from 2012 to 2033) 

Project	Value	Type	Year
A	X	Income	2012
A	Y	Cost	2012
A	X2	Income	2013
A	Y2	Cost	2013
B	XX	Income	2012
B	YY	Cost	2012

What I want to visualise: 

Period	2012-2021	2013-2022	2014-2023	2015-2024	2016-2015	2017-2026	2018-2027	2019-2027
Income
Expense
Net

Any suggestions for achieveing this?

Thanks

Thanks for the reply, 

Yes that's what I'm looking for! Thanks for the help. 

However, since the totalrow in the matrix calculates the total wrong (for instance in your example, (-235)+(-155) isn't 155), how would I go about and get a correctly displayed Total? 

Thanks
