Plot(fs, x0, x1)
Plot(fs, x0, x1, l; style, config, kwargs...)

For each function in f in fs, construct a scatter trace that plots f from x0 to x1, using the layout l. All keyword arguments are applied to all constructed traces.

Plot(f, x0, x1)
Plot(f, x0, x1, l; style, config, kwargs...)

Construct a plot of f from x0 to x1, using the layout l. All keyword arguments are applied to the constructed trace.

Plot(y)
Plot(y, l; kwargs...)

Build a scatter plot and set y to y. All keyword arguments are passed directly as keyword arguments to the constructed scatter.

Plot(x, y)
Plot(x, y, l; kind, style, config, kwargs...)

Build a plot of with one trace of type kindand set x to x and y to y. All keyword arguments are passed directly as keyword arguments to the constructed trace.

NOTE: If y is a matrix, one trace is constructed for each column of y

NOTE: If x and y are both matrices, they must have the same number of columns (say N). Then N traces are constructed, where the ith column of x is paired with the ith column of y.

addtraces!(p::Plot, i::Int, traces::AbstractTrace...)

Add trace(s) at a specified location in the Plot's array of data.

The new traces will start at index p.data[i]

addtraces!(p::Plot, traces::AbstractTrace...)

Add trace(s) to the end of the Plot's array of data

Draw a circle from ((x0+x1)/2, (y0+y1)/2)) with radius (|(x0+x1)/2 - x0|, |(y0+y1)/2 -y0)|)

deletetraces!(p::Plot, inds::Int...) =

Remove the traces at the specified indices

extendtraces!(::Plot, ::Dict{Union{Symbol,AbstractString},AbstractVector{Vector{Any}}}), indices, maxpoints)

Extend one or more traces with more data. A few notes about the structure of the update dict are important to remember:

• The keys of the dict should be of type Symbol or AbstractString specifying the trace attribute to be updated. These attributes must already exist in the trace
• The values of the dict must be a Vector of Vector of data. The outer index tells Plotly which trace to update, whereas the Vector at that index contains the value to be appended to the trace attribute.

These concepts are best understood by example:

# adds the values [1, 3] to the end of the first trace's y attribute and doesn't
# remove any points
extendtraces!(p, Dict(:y=>Vector[[1, 3]]), [1], -1)
extendtraces!(p, Dict(:y=>Vector[[1, 3]]))  # equivalent to above

# adds the values [1, 3] to the end of the third trace's marker.size attribute
# and [5,5,6] to the end of the 5th traces marker.size -- leaving at most 10
# points per marker.size attribute
extendtraces!(p, Dict("marker.size"=>Vector[[1, 3], [5, 5, 6]]), [3, 5], 10)

hline(y, fields::AbstractDict=Dict{Symbol,Any}(); kwargs...)

Draw horizontal lines at each point in y that span the width of the plot

Draw a line through the points (x0, y0) and (x1, y2)

movetraces!(p::Plot, src::AbstractVector{Int}, dest::AbstractVector{Int})

Move traces from indices src to indices dest.

Both src and dest must be Vector{Int}

movetraces!(p::Plot, to_end::Int...)

Move one or more traces to the end of the data array"

Draw an arbitrary svg path

prependtraces!(p::Plot, update::AbstractDict, indices::AbstractVector{Int}=[1],
                maxpoints=-1)

The API for prependtraces is equivalent to that for extendtraces except that the data is added to the front of the traces attributes instead of the end. See Those docstrings for more information

Draw a rectangle linking (x0,y0), (x1,y0), (x1,y1), (x0,y1), (x0,y0)

relayout!(l::Layout, update::AbstractDict=Dict(); kwargs...)

Update l using update dict and/or kwargs

relayout!(p::Plot, update::AbstractDict=Dict(); kwargs...)

Update p.layout on using update dict and/or kwargs

The restyle! method follows the semantics of the Plotly.restyle function in plotly.js. Specifically the following rules are applied when trying to set an attribute k to a value v on trace ind, which happens to be the ith trace listed in the vector of inds (if ind is a scalar then i is always equal to 1)

• if v is an array or a tuple (both translated to javascript arrays when

json(v) is called) then p.data[ind][k] will be set to v[i]. See examples below

• if v is any other type (any scalar type), then k is set directly to v.

Examples

# set marker color on first two traces to be red
restyle!(p, [1, 2], marker_color="red")

# set marker color on trace 1 to be green and trace 2 to be red
restyle!(p, [2, 1], marker_color=["red", "green"])

# set marker color on trace 1 to be red. green is not used
restyle!(p, 1, marker_color=["red", "green"])

# set the first marker on trace 1 to red, the second marker on trace 1 to green
restyle!(p, 1, marker_color=(["red", "green"],))

# suppose p has 3 traces.
# sets marker color on trace 1 to ["red", "green"]
# sets marker color on trace 2 to "blue"
# sets marker color on trace 3 to ["red", "green"]
restyle!(p, 1:3, marker_color=(["red", "green"], "blue"))

restyle!(p::Plot, update::AbstractDict=Dict(); kwargs...)

Update all traces using update dict and/or kwargs

restyle!(p::Plot, ind::Int=1, update::AbstractDict=Dict(); kwargs...)

Update p.data[ind] using update dict and/or kwargs

restyle!(::Plot, ::AbstractVector{Int}, ::AbstractDict=Dict(); kwargs...)

Update specific traces at p.data[inds] using update dict and/or kwargs

restyle!(gt::GenericTrace, i::Int=1, update::AbstractDict=Dict(); kwargs...)

Update trace gt using dict/kwargs, assuming it was the ith ind in a call to restyle!(::Plot, ...)

savefig(
    io::IO,
    p::Plot;
    width::Union{Nothing,Int}=nothing,
    height::Union{Nothing,Int}=nothing,
    scale::Union{Nothing,Real}=nothing,
    format::String="png"
)

Save a plot p to the io stream io. They keyword argument format determines the type of data written to the figure and must be one of png, jpeg, webp, svg, pdf, eps, json, or html. scale sets the image scale. width and height set the dimensions, in pixels. Defaults are taken from p.layout, or supplied by plotly

savefig(
    p::Plot, fn::AbstractString;
    format::Union{Nothing,String}=nothing,
    width::Union{Nothing,Int}=nothing,
    height::Union{Nothing,Int}=nothing,
    scale::Union{Nothing,Real}=nothing,
)

Save a plot p to a file named fn. If format is given and is one of png, jpeg, webp, svg, pdf, eps, json, or html; it will be the format of the file. By default the format is guessed from the extension of fn. scale sets the image scale. width and height set the dimensions, in pixels. Defaults are taken from p.layout, or supplied by plotly

stem(; y, stem_color, stem_thickness, kwargs...)

Creates a "stem" or "lollipop" trace. It is implemented using plotly.js's scatter type, using the error bars to draw the stem.

Keyword Arguments:

• All properties accepted by scatter except error_y, which is used to draw the stems
• stem_color - sets the color of the stems
• stem_thickness - sets the thickness of the stems

Apply both restyle! and relayout! to the plot. Layout arguments are specified by passing an instance of Layout to the layout keyword argument.

The update Dict (optional) and all keyword arguments will be passed to restyle

Example

julia> p = Plot([scatter(y=[1, 2, 3])], Layout(yaxis_title="this is y"));

julia> print(json(p, 2))

Given the number of rows and columns, return an NTuple{4,Float64} containing (width, height, vspace, hspace), where width and height are the width and height of each subplot and vspace and hspace are the vertical and horizonal spacing between subplots, respectively.

trace_map(p::Plot, axis::Symbol=:x)

Return an array of length(p.data) that maps each element of p.data into an integer for which number axis of kind axis that trace belogs to. axis can either be x or y. If x is given, return the integer for which x-axis the trace belongs to. Similar for y.
