No plot in curve fitting tool

Dear Sir or Madam,

I have Data in the curve fitting tool, and the fit works. But no plot is shown. In the plot window is "Select data to fit or surface":

This is the result of the fit, but no plot!

Linear model Poly21: f(x,y) = p00 + p10*x + p01*y + p20*x^2 + p11*x*y where x is normalized by mean 116.2 and std 18.48 and where y is normalized by mean 400 and std 282.9 Coefficients (with 95% confidence bounds): p00 = 0.4757 (0.4649, 0.4865) p10 = -0.636 (-0.6543, -0.6178) p01 = 0.3375 (0.3284, 0.3467) p20 = 0.02451 (0.01931, 0.02971) p11 = -0.3553 (-0.3635, -0.3471)

Goodness of fit: SSE: 1632 R-square: 0.6116 Adjusted R-square: 0.6115 RMSE: 0.3298

Pleas help me

Sincerely Björn
