I'm not sure I know exactly how to use the Minkowski diagram. For
example, let's say you have a stationary observer and a moving
observer, and an event somewhere, for which the coordinates are x and
t in the stationary frame and x' and t' in the moving frame. How do
you get t', for example, from the Minkowski diagram?

Through the given point, draw a line parallel to the x' axis. The
intersection of that line and the t' axis gives the value of t' for
the given point.

Yes, if you multiply with sqrt(1-v^2)/sqrt(1+v^2).
See my replies.
