Plotting Expenses

I'm trying to create a stacked column chart, and I'm having trouble trying to get things to scale properly. My expensed, encumbered, and preencumbered amounts range from nothing to millions of dollars, and I have about 20 categories in my charts. To get them to show, reasonably, I want to use the logarithmic scale. However, my zero amounts mess that up, as Excel gives a messsage that I can't use zeros in a logarithmic scale. How would I get the chart to ignore my zero amounts, or how would I get my millions and my 1 and 2 cent amounts to coexist in the same chart otherwise? Any help is highly appreciated.

Thanks,
John
