Chart showing different data than listed

I'm doing an energy chart for 3 different buildings. Column 1 has the
months, column 2 has the dollar amount is for Bldg 1. Column 3 is for the
dollar amount for Bldg 2 and column 4 ist the dollar amount for Bldg 3.

On the chart, Bldg 1's data shows correctly @ 2300. But Bldg 2's data is
showing 2900 when it should show 530. Bldg 3's data is showing 3500 when it
should show 620. It is the same problem (figures different) for the rest of
the year.

I've gone in and made sure that it is pulling data from the correct areas
and it is. It's just not reflecting accurately in the chart.

I can't find the corresponding figures for what the chart shows for Bldgs 2
and 3. It looks like the figures are just a repeat of Bldg 1's data, upped a
bit. And that's not what has been entered on my spreadsheet.

I know it's hard to figure out from just my description, but I'd appreciate
any help.
