Investigate general method for saving of raw plot objects with pickle
https://stackoverflow.com/questions/4348733/saving-interactive-matplotlib-figures
Pickle seems to save general "objects" and enables loading them again. This general approach would allow to "load into" the workflow after the scripts to process the data have run. With big data or complicated calculations this could take more time than initially wanted and intermediate data might not be saved.
Additionally we can add the ID to this as metadata in a general way (to be confirmed).
