Reporting EXCEL trendline Plotting BUG

I am having difficulty Using 2007 excel trendline functions for polynomials on data sets (xy scatter plots).
after plotty x and y and adding a trendline with the displayed function I tried to back calculate the values from the function to validate the trendline.
the equation does not match the shape of the trendline at all which is very Odd> I replotted the results in Matlab and it seems that the coefficient infront of the x^3 term does not show sufficient significant digets.
Does anyone know how to increase the significant figures in the trendline equation or know how to fix this error?

here is a sample of the x y data that I am trying to validate the trendline for.

Thanks, I did manage to solve the problem just after I posted the request. - left click on the trendline- format trendline label and - number precision.

Thanks anyway. I may have questions in the future. You any good with matlab? or know a good forum/
