Help please! I have a manipulated graph programmed in Version 11, which worked perfectly, but when I run it with version 12, it works, but a "red" area appears with the error "A tick position in the value of the Ticks option should be a number. ". I have tried many alternatives, but I can't figure it out. Please check the attached file. Thanks for your help!
Thanks Gianluca! It has saved my afternoon so that I can watch Serie A matches later!
Remove one level of curly braces in your specification of Ticks:
Ticks
Ticks -> {{0.835484 (60. + 1.19691 \[Gamma])}, Automatic}
The way you did it, Mathematica was expectig a couple {position,label}, and if only found {position}.
{position,label}
{position}
