I want to draw a circle of 4mm with minus sign inside it. I have set the m
style:
\tikzstyle{m}=[circle, thin, draw=red, fill=red, minimum size=4mm]
however the minus sign extends the circle. I want the sign to almost fill the circle. I tried to change the line to be:
\tikzstyle{m}=[circle, thin, draw=red, fill=red, size=4mm]
but it didn't work.
How can I set the circle size to be fixed?

TikZ automatically adds separation between the text and the node border. When setting a minimum size for a node, it's usually a good idea to set
inner sep=0pt
