! err602_shade_line_lev.jnl
! Bug 904.
! SHADE/LEV does not keep same levels after a SHADE/LINE
! Was due to fact that SHADE/LINE makes PPL SHADE  call
! followed by PPL CONTOUR/OVER call, but without indicating
! that the same contour levels should be used.

! Note that SHOW SYM LEV* indicates that the SHADE/LINE/KEY changes the levels.

let a = {1,1}* ysequence({-.29,1.09})
set view ul; shade/key a; sh sym lev*
set view ur; shade/lev a; sh sym lev*
set view ll; shade/line/key a; sh sym lev*
set view lr; shade/lev a; sh sym lev*
