[slack] <Qiyao Wei> Hi all, I am trying to follow this tutorial to plot an integrator object (https://diffeq.sciml.ai/stable/basics/integrator/), but received the following error. For completeness, I also post the segment of code where I use the plot function. Any help is appreciated. Thanks a lot!
