Arrhenius Graphic

hey guys!!!
I’m looking to understand and be able to plot the Arrhenius graph using GULP.
I managed to run the calculation of the diffusion coefficient for my material, but I don’t know what to do after that, which results I should analyze.
this graph is made using the diffusion coefficient as a function of temperature.
Could someone tell me how this graph is made? How is the temperature variation done and what is the result that I use in the output file?
