I wroted the code likt this above.
but it seems totally wrong.
the patch should be narrower than trajectory, because i set the range with percentile 2.5 and 97.5.
how can the patch be more bigger than the trajectory?
I thought at least the patch's size is as same as trajectory's size.

The plot appears they are related given shapes shown, but could be scaled differently, for example.
