val simple : 
  ?width:Num.t ->
  ?height:Num.t ->
  ?padding:Num.t ->
  ?fill:Color.t list ->
  ?perspective:bool ->

simple l draws an histogram from a list l of floating-point values.

parameter width
Total width of the histogram (default: 100 bp)

parameter height
Total height for the histogram (default: 200 bp)

parameter fill
The colors used to draw the successive blocks; it is used circularly

parameter padding
Horizontal space between two blocks

parameter hcaption
See module Plot

parameter vcaption
See module Plot

parameter hlabel
Labels for each block

parameter vlabel
See module Plot

parameter histlabel
Add a label to each block; the first component controls the placement of the label; the second component, of type insideBox, controls the label itself, which is either the numerical value of the block (i.e. the float) or a user picture

val compare : 
  ?width:Num.t ->
  ?height:Num.t ->
  ?padding:Num.t ->
  ?fill:Color.t list ->
  ?perspective:bool ->

  ?histlabel:(Command.vposition * Picture.t list labels) ->
  ?vlabel:Plot.labels ->
  ?hlabel:Picture.t list ->
  float list list ->
  Command.t

compare l draws a comparative histogram from a list l of floating-point lists. For optional arguments, see function simple above.

val stack : 
  ?width:Num.t ->
  ?height:Num.t ->
  ?padding:Num.t ->
  ?fill:Color.t list ->

  ?histlabel:(Command.vposition * Picture.t list labels) ->
  ?vlabel:Plot.labels ->
  ?hlabel:Picture.t list ->
  float list list ->
  Command.t

compare l draws a stacked histogram from a list l of floating-point lists. For optional arguments, see function simple above.
