Try changing the position expression to use nesting:
ELEMENT: point(position(P01_pat/Sequence*Pk), color.exterior(Teatment))

This will construct a panel for each value of Sequence.  Within each
panel, the X axis (P01_pat) will only show categories that occur within
that panel.  So each panel will have a different X axis.

Note that Pat. No. 7 will not appear in the first panel as you expected,
because there is no Pat. No. 7 in the data.
