combining year and month in same axis (stacked bar)

Hi experts,

I got one complicated requirement.

SAP BW: 7.4 SP7

BO 4.1 Sp4

Connection: BEx

I have an requirement in one stacked graph i get

Current month till End of the current year; Next year; Next Year +1; Remain (jan til currentmonh-1, nextyear+3)

For example

if we are in August

Aug 2014 till Dec 2014; FY2015; FY2016; Jan till Jul 2017

so the graph going to have 5 bars + 1 + 1 + 1

if we are in September for example

Sept 2014 till Dec 2014; FY2015; FY2016; Jan till August 2017

so the graph going to have 4 bars +1 +1 +1

I'm using the Fiscal Period (0fiscper)

and one Kf

How can I achieve this axis combining months and years?

Thanks.

Regards,
