Plotting float Arrays.

val y : 
  Viewport.t ->
  ?const_base:bool ->
  ?base:float array ->
  ?fill:bool ->
  ?fillcolor:Color.t ->
  ?style:style ->
  ?const_y:bool ->
  float array ->
  unit

y vp yvec draws the set of points (i, yvec.(i)).

parameter style
the style used for the plot. The default style is `Marker "O" which means data points are marked by a small disk. See Archimedes.style for a full list.

parameter fill
whether to fill the surface between the base and the values yval.

parameter fillcolor
the filling color (default: Color.white_smoke).

parameter const_y
whether the input vector yvec will not be modified anymore (so there is no need to cache its current values).

parameter base
for the styles `Lines, `Markers, and `Linesmarkers, it gives the bottom of the filling zone. For the styles `Impulses and `Bars w, it is the Y value above which the boxes (of heights given by yvec) are drawn. For the style `HBars, it is the (signed) distance to the Y axis at which the horizontal bar starts.

parameter const_base
same as const_y for the base.

val xy : 
  Viewport.t ->
  ?fill:bool ->
  ?fillcolor:Color.t ->
  ?style:style ->
  ?const_x:bool ->
  float array ->
  ?const_y:bool ->
  float array ->
  unit

xy cp xvec yvec draws the set of points (xvec.(i), yvec.(i)). The optional arguments are similar to Array.y.

raises Invalid_argument
if xvec and yvec do not have the same length.
See Array.y for the meaning of optional arguments.

val xy_pairs : 
  Viewport.t ->
  ?fill:bool ->
  ?fillcolor:Color.t ->
  ?style:[ `Lines | `Markers of string | `Linesmarkers of string ] ->
  (float * float) array ->
  unit

See Array.xy. The only difference is that this function takes an array of couples (x,y) instead of two arrays, one for x and a second of y.

val stack : 
  Viewport.t ->
  ?fill:bool ->
  ?fillcolors:Color.t array ->
  ?style:style ->
  ?const:bool ->
  float array array ->
  unit

stack yvecs plot the data in a stacked fashion, the Y values contained in yvecs.(i) are represented as the deviation above yvecs.(i-1). This makes sense only if the data is non-negative.

parameter style
how to represent each data point. Default `Bars 0.5.

parameter colors
the colors for the data lines.

parameter fill
whether to fill the boxes or area under the data points. Default: true.

parameter fillcolors
the ith color is used to fill the area under the data points yvecs.(i). If the array is empty, a default palette is used. If there are less colors than vectors in yvecs, they are used in a circular way.

parameter const_y
whether the input vector yvec will not be modified anymore (so there is no need to cache its current values).
