[Gnuplot-info] All points y value undefined...

[Julien D. <Jul...@da...>]

Hi everyone,
I am trying to plot the gamma function, and have this error message....

gnuplot> plot 0.6*gamma(101)*gamma(100.6-x)/ 
(gamma(100+0.6+1)*gamma(100-x+1))
                                                                              ^
          all points y value undefined!


I can't believe this is not defined ! I don't understand the error  
message. help???
