Hi,
I am modifying a graph that I borrowed from a colleague. I hope some of you might be able to help me figure out the following questions I have.
1. What is the purpose of
\makebox(0,0)[cc]{\footnotesize{$p_0$}}
I know what \makebox does but I'm not sure what (0,0) is doing or why there are two c's in the position parameter.
2. Is there a better way to handle the coordinates in the \put commands? If I change the xunit or yunit, then all the positions must be individually adjusted.
Any other suggestions to streamline the code would be appreciated.
Thanks,
