Old code version 8 does not work in version 12

Dear all,
I got an old mathematica script, which worked in Mathematika 8.0, but doesn’t work in the new version. I want to plot my raw data togehter with fitted data in one graph. In particular it’s these lines that do not work:

mm={Inn[In0,Rn,Ru,knu,kun,T],Iuu[Iu0,Rn,Ru,knu,kun,T],Inu[In0,Rn,Ru,knu,kun,T],
    Iun[Iu0,Rn,Ru,knu,kun,T]};

Show[ListPlot[dd],Plot[Evaluate[mm/.fitparams],{T,0,2}],PlotRange->{0,1}]

Evaluate[mm/.fitparams]

I think it’s the evaluate statement that does not work.

How is this done properly in the newer version?

Thanks for your help,
Julia

Hi Julia,

There is not enough information provided to understand the problem and suggest a solution.

  • Does ListPlot[dd] work?
  • What is the result of evaluating Evaluate[mm/.fitparams]?
  • What does Show return? Error? Empty plot?
