Hi,
I'm having difficulties creating an binomial option tree. The tree is
fine, however, LYX refuses to let me create two lines on top of each
other at the nodes. All fractions and \underset work, but I would like
the entries (S_0u / f_u) to be equally sized in two lines at each node
without fraction lines. Neither tables nor array/align,
*\txt{S_0ud\\f_ud} etc shows up in the figure. Is there anyway around
this in LYX or do I need to write it in TEX?
My entry looks like:
\xymatrix{
& & & & S_0u^2\\
& & S_0u \ar[urr] \ar[drr] & & \\
S_0 \ar[urr] \ar[drr] & & & & *{\txt<4pc>{S_0ud\\ f_ud}} \\
& & S_0d \ar[urr] \ar[drr] & & \\
& & & & S_0d^2}
Best regards,
Tomi
