Stacked Bar Chart Workaround

[RussellSenior]

I posted this in the idea exchange, but I'm stumped on a workaround. 

I would like to display the total effect of multiple inputs to a process, while also showing the relative impact of each input.  The workaround in the link below works when all impacts are positive.  When one of the impacts is negative, it isn't shown, since it gets hidden by the bar before it.  In excel, any negative impacts are shown below the x-axis.

I've also attached an excel example, just in case what I'm looking for isn't clear.  So, barring developing some complicated logic to deal with negative impacts to the total output, how can I show relative impact of multiple inputs to a total?  It doesn't have to be a bar chart, that's just what we have started with.

Hi Russell;

A quick workaround would be changing the fill pattern of the bar. There are several options, I used for example:

 curve.Shape.Settings.Filling.Pattern = eFillPatternLeftDiagonal

And this is what I got:

 

In the DIAdem help you can find what other fill patterns are available:

My example program is another workaround for creating a bar chart:
