So, now that I actually have a spreadsheet program, I'm trying to be financially responsible and set up my finances in Numbers. The basic setup is as follows: 1. I enter actual monthly data for my expenses then... 2. It calculates a SUM for total monthly expenses then... 3. I have it multiply that number by 3 and 12 to come up with an Estimated Quarterly and Yearly Expenses respectively. 4. Then, I have it chart those numbers so I can visualize fluctuation over time The problem is that I am dealing with very large numbers and the SUM fields for the months that haven't happened yet are, of course, 0's. So I can't really view slight variations in these numbers because of the scale of the chart. Because the SUM automatically calculates a 0, I can't set the maximum or minimum in the Inspector panel to not chart that data. Is there anyway I can change the formula in the cells to have it not register in the chart until the value is not zero? P.S. I realize these numbers aren't really a great indicator of anything, I just want to see the flux so I can get a good idea how my estimates are working until I have enough data to formulate a steady number in average monthly expenses column.
