I have installed stata kernel to jupyter lab with the following codes (following the steps from kylebarron.dev/stata_kernel):
pip install stata_kernel
python -m stata_kernel.install
It works for stata codes. But when I want to plot graphs with stata codes, the graph is created in .stata_kernel_cache folder but not displayed on the jupyter output panel. Here are the result from a sample and the result generated when I tried the sample code by myself:

You can see my jupyter only saved the image files but not display the graph on the output panel. Could someone tell me why?
