Net Worth barchart suggestion

[Ben Stanley]

Hi,

I had an idea about how to improve the net worth barchart. See

At the moment, Assets and Liabilities are plotted on the same axis. 
Really, Liabilities are the opposite of Assets. A negative liability is 
a posotive asset. The current graph makes this fact confusing. The 
suggested format will help to clear this up. (Note that if you do have a 
negative asset or a negative liability, I'm not quite sure how to draw 
it in this format :-) )

The net worth is marked on my drawing by extra horizontal lines, but I 
think that needs to be improved.

Ben.
