Main interface
val create : ?verbose:bool -> ?path:string -> unit -> t
create ?verbose ?path ()
creates a channel to a Gnuplot process with the executable given bypath
. Ifverbose
is true then plotting commands print debug information on standard output.
val close : t -> unit
close t
closes the channel to the Gnuplot process.
val with_ : ?verbose:bool -> ?path:string -> (t -> 'a) -> 'a
with_ ?verbose ?path f
creates a channel to a Gnuplot process, usingcreate
. Then it callsf
with this channel, and makes sure toclose
the channel oncef
is done.
val set : ?output:Output.t -> ?title:string -> ?use_grid:bool -> ?fill:Filling.t -> ?labels:Labels.t -> ?custom:(string * string) list -> t -> unit
set ?output ?title ?fill ?labels ?custom t
sets parameters of the Gnuplot session.- parameter custom
since 0.7 to specify other settings (set/unset pairs)
val unset : ?fill:Filling.t -> ?labels:Labels.t -> ?custom:(string * string) list -> t -> unit
unset ?fill ?labels t
resets parameters of the Gnuplot session.
val plot : ?output:Output.t -> ?title:string -> ?use_grid:bool -> ?fill:Filling.t -> ?range:Range.t -> ?labels:Labels.t -> ?format:string -> ?logscale:(string * int option) -> ?custom:(string * string) list -> t -> Series.t -> unit
plot t series
plots a single dataseries
. The parameters for filling, range, etc are optional.
val plot_many : ?output:Output.t -> ?title:string -> ?use_grid:bool -> ?fill:Filling.t -> ?range:Range.t -> ?labels:Labels.t -> ?format:string -> ?logscale:(string * int option) -> ?custom:(string * string) list -> t -> Series.t list -> unit
plot_many t series
creates a plot of multiple dataseries
. The parameters for filling, range, etc are optional.
val plot_func : ?output:Output.t -> ?title:string -> ?use_grid:bool -> ?fill:Filling.t -> ?range:Range.t -> ?labels:Labels.t -> ?logscale:(string * int option) -> ?custom:(string * string) list -> t -> string -> unit
plot_func t f
draws a graph of the functionf
given as a string. The functionf
has to be specified in the Gnuplot format, eg `sin(x)`. The parameters for the filling, range, etc are optional.
