ds 'hist 6' only shows the starting and ending values, not the
intermediate values.

This is more interesting, from my point of view:

hist f.
' O' {~ (] !~ [: i. >:) >/ [: i. [: >./ ] !~ [: i. >:
ds '('' O'' {~ (] !~ [: i. >:) >/ [: i. [: >./ ] !~ [: i. >:) 6'

Also interesting comparing:

ds '('' O'' {~ (] !~ i.@>:) >/ [: i. ] >./@:!~ i.@>:) 6'

ds '('' O'' {~ (!~ i.@>:) >/ i.@(>./@:!~ i.@>:)) 6'

ds '('' O'' {~ (i.@>: ! ]) >/ i.@(i.@>: >./@:! ])) 6'

and contrasting:

ds '('' O'' {~ (] >/ i.@(>./))@(i.@>: ! ])) 6'

Yes, and Ye Dic spells it out:

m"(-r) y is equivalent to m"(0>.(#$y)-r)"_

Note the final "_
