That's basically it for me. Sometimes, I generate data from some very large programs and it's more practical and scalable to process that data outside of Python. In addition, most often, I put the plots inside of a LaTeX generated report or slides. In gnuplot, I can generate a piece of LaTeX code that will automatically match the fonts when the document changes. Does anyone know if the same functionality can be found in matplotlib or do we have to change the fonts by hand?
