Hi, my name is Marcelo Musri, from Argentina. Someone could help me customize currency format in my docker Superset. Thanks a lot

Hi @marcelo-musri this PR is for an experimental feature not available on the main superset branch. For a better forum to ask technical questions please join the superset community slack or go to the discussions tab, as these PR pages are meant for conversations concerning the specific pull requests.
Currency formatting is available in different ways, for example by customizing a big number chart or by editing a dataset and customizing the metric currency. If you have further questions please reach out in one of the forums mentioned above. Good luck!
