Waterfall variation by sales type

[goyasor]

Hi,

I'm trying to create a waterfall that shows:

First Bar:  2015 total

Middle Bars:  Year over Year Change

End Bar:  2016 Total 

For example:

First Bar:  2015 total  = 20M Cars

Middle Bars:  GM+400K, Ford -100K, Toyota-200K, Honda+500K, Chrysler+400K

End Bar:  2016 total = 21M Cars

I'm having trouble creating this. Does anyone know how I could achieve what I'm after? 

Many thanks.
