Try right-clicking the label with the equation, then choose the option to format it (not using english excel, sry) and change the design to "number" with the desired amount of digits. The numbers are still off, but way better than 8E+06. Seriously, Excel is bad for scientifical use. Every spreadsheet application should be able to determine 2nd-order polynomials correctly for being considered to use. I never use it but to take a first look, and most of the time is use GNUplot even for that purpose. Think it's called office because its for office use, not for mathematical or scientifical use ;) Hi,

I'm sure there are other nice graphing programs out there, but we just don't have the time or money to try others out. Hi Tinsae,
