I'm writing a thesis-like document and I have sketches/figures made in TikZ and plots/graph made in gnuplot with the epslatex terminal. In the gnuplot manual it says if the font is not specified it will inherit the font and size from the context in the document. I'm not sure how TikZ does it.
I would like to reduce the font size of the text in the figures. How do I do that? In case it matters, I'm using the KOMA
scrreprt class. I would very much like a way to do it so I don't have to modify the TikZ code or the tex-file produced by gnuplot. This question is not about the figure captions but the text in the figures themselves, although I will change the caption font size as well, obviously :)
