What is the font of lefse default plots?

hey, my friends,
I wanna know the font of the lefse plots so that I can use AI to modify the font format. please give me a hand. If you can provide me with a font file on the Window platform, I will appreciate your kindness.

thanks very much!

It is probably one of the default Python:matplotlib fonts. If you install matplotlib it ought to install those fonts along with it.

thanks for your reply, and I will have a try.
