Pivot Table turning out oddly

Hello,

I'm hoping someone will be able to help with this. I've been tasked with creating a pivot table for spreadsheet with TONS of data (15 columns, 235,000 Rows approx).
When I make the pivot charts, the charts appear to look odd. The data on the new page all seems to be correct (this is a guess, obviously). The chart, however seems have rearranged the data. The chart fluctuates up and down violently in a way that is not actually possible (see attached picture).

Was wondering why this was the case, if you have any suggestions. Capture.JPG

Let me know if you need any additional info.

I am using MS Excel 2010.

Thanks,

my best guess is the chart reflects the data in your table. I suggest you look at the data. has the pivot table changed the order of your data?
