I am using tikz for many pictures in my thesis, but I am not really clear on how to scale the pictures to fit my needs... I generally use "\node"s which I connect with line segments. I draw and fill the nodes to make them small black circles. I use a different node style to create nodes without draw/fill to place text in them.
Unfortunately most of the coordinates for nodes are generated by another program. As a consequence, the coordinates are all in between 0 and 1. Since that is much too small for me, I scale the pictures up by passing scale=... to the tikzpicture. Unfortunately this also scales the size of the nodes and the fontsize which is equally annoying. I would like to scale the coordinates of all my nodes without scaling either the node or the font size. Is that possible using tikz?
