Is there a chunk option or something similar that achieves the same results? 回答1: Use the option self

问题 How can I prevent a specific plot to be shown in Jupyter notebook? I have several plots in a notebook but I want a subset of them to be saved to a file and not shown on the notebook as this slows considerably.
