```Dear Rui,
Many thanks. It is indeed close to what I am looking for apart from
the issues on the axes.

I am attaching the result plot. The minimum and maximum values of y1
are respectively -5.470919 and 1.298329 while they are 0.0002937659
and 4.808186 for y2.

New problems are: (1) I can't labelled the axis as (x1,x2) persist
when I tried to label the axes. (2) The two plots are merging at some
points. I only want them close but not merging as that does not allow
for meaningful comparison.

It would be great if you could adjust the code further to minimize
these problems.

Thank you.
Best wishes
Ogbos
