I have basically loosely followed this link
http://www.angelsbiblog.com/2012/02/improve-data-visualization-in-your-ssrs.html
and made the below linked graph. Its one dataset, I have simply pulled in Gross Profit and Sales fields. Neither are calculated fields. I put them in 2 different chart areas, but then as per that link, made the chart areas the same size so they overlay.

what I want to do, is as illustrated by that inserted green arrow in the graph image, is raise up the Zero line for the Income bars (yellow) to the same level as the Profit/Loss(Blue-Red).
I also want the vertical axis to preferably have the same axis, so i dont have to have that secondary axis on the right.
However the main thing is the graphs sharing their zero line. I have made the Profit bars smaller I width than the yellow bars, so in a month of blue profit, it would simply sit neatly inside the yellow income bar.
I haven't added expenses because it should be obvious what they are by the height differential btw Income to Profit or to the Loss.
Any ideas much appreciated.
