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'
