map_once(closure, inputs::Node....)::Node

Like Reactive.foreach, in the sense that it will be preserved even if no reference is kept. The difference is, that you can call map once multiple times with the same closure and it will close the old result Node and register a new one instead.

``` function test(s1::Node) s3 = maponce(x-> (println("1 ", x); x), s1) s3 = maponce(x-> (println("2 ", x); x), s1)

Main plotting signatures that plot/plot! route to if no Plot Type is given

`poly(vertices, indices; kwargs...)`
`poly(points; kwargs...)`
`poly(shape; kwargs...)`

Plots a polygon based on the arguments given. When vertices and indices are given, it functions similarly to mesh. When points are given, it draws one polygon that connects all the points in order. When a shape is given (essentially anything decomposable by GeometryTypes), it will plot decompose(shape).

poly(coordinates, connectivity; kwargs...)

Plots polygons, which are defined by coordinates (the coordinates of the vertices) and connectivity (the edges between the vertices).

Theme

When a shape is given (essentially anything decomposable by GeometryTypes), it will plot decompose(shape).

record(func, scene, path, iter; framerate = 24)

This is simply a shorthand to wrap a for loop in record.

Example:

    scene = lines(rand(10))
    record(scene, "test.gif", 1:100) do i
        scene.plots[:color] = Colors.RGB(i/255, 0, 0) # animate scene
    end

record(func, scene, path; framerate = 24)
record(func, scene, path, iter; framerate = 24)

Records the Scene scene after the application of func on it for each element in itr (any iterator). func must accept an element of itr.

The animation is then saved to path, with the format determined by path's extension. Allowable extensions are:

• .mkv (the default, doesn't need to convert)
• .mp4 (good for Web, most supported format)
• .webm (smallest file size)
• .gif (largest file size for the same quality)

.mp4 and .mk4 are marginally bigger and .gifs are up to 6 times bigger with the same quality!

Typical usage patterns would look like:

record(scene, "video.mp4", itr) do i
    func(i) # or some other manipulation of the Scene
end

or, for more tweakability,

record(scene, "test.gif") do io
    for i = 1:100
        func!(scene)     # animate scene
        recordframe!(io) # record a new frame
    end
end

If you want a more tweakable interface, consider using VideoStream and save.

Examples

scene = lines(rand(10))
record(scene, "test.gif") do io
    for i in 1:255
        scene.plots[:color] = Colors.RGB(i/255, (255 - i)/255, 0) # animate scene
        recordframe!(io)
    end
end

or

scene = lines(rand(10))
record(scene, "test.gif", 1:255) do i
    scene.plots[:color] = Colors.RGB(i/255, (255 - i)/255, 0) # animate scene
end

record_events(f, scene::Scene, path::String)

Records all window events that happen while executing function f for scene and serializes them to path.

recordframe!(io::VideoStream)

Adds a video frame to the VideoStream io.

Like get!(f, dict, key) but also calls f and replaces key when the corresponding value is nothing

replay_events(f, scene::Scene, path::String)
replay_events(scene::Scene, path::String)

Replays the serialized events recorded with record_events in path in scene.

rotate!(scene::Transformable, axis_rot::Quaternion)
rotate!(scene::Transformable, axis_rot::AbstractFloat)
rotate!(scene::Transformable, axis_rot...)

Apply an absolute rotation to the Scene. Rotations are all internally converted to Quaternions.

rotate!(Accum, scene::Transformable, axis_rot...)

Apply a relative rotation to the Scene, by multiplying by the current rotation.

rotate_cam!(scene::Scene, theta_v::Number...)
rotate_cam!(scene::Scene, theta_v::VecTypes)

Rotate the camera of the Scene by the given rotation.

scale!(t::Transformable, x, y)
scale!(t::Transformable, x, y, z)
scale!(t::Transformable, xyz)
scale!(t::Transformable, xyz...)

Scale the given Transformable (a Scene or Plot) to the given arguments. Can take x, y or x, y, z. This is an absolute scaling, and there is no option to perform relative scaling.

select_rectangle(scene; kwargs...) -> rect

Interactively select a rectangle on a scene by clicking the left mouse button, dragging and then un-clicking. The function returns an observable rect whose value corresponds to the selected rectangle on the scene. In addition the function plots the selected rectangle on the scene as the user clicks and moves the mouse around. When the button is not clicked any more, the plotted rectangle disappears.

The value of the returned observable is updated only when the user un-clicks (i.e. when the final value of the rectangle has been decided) and only if the rectangle has area > 0.

The kwargs... are propagated into lines! which plots the selected rectangle.

update_limits!(scene::Scene, new_limits::HyperRectangle, padding = Vec3f0(0))

This function updates the limits of the given Scene according to the given HyperRectangle.

A HyperRectangle is a generalization of a rectangle to n dimensions. It contains two vectors. The first vector defines the origin; the second defines the displacement of the vertices from the origin. This second vector can be thought of in two dimensions as a vector of width (x-axis) and height (y-axis), and in three dimensions as a vector of the width (x-axis), breadth (y-axis), and height (z-axis).

Such a HyperRectangle can be constructed using the FRect or FRect3D functions that are exported by AbstractPlotting.jl. See their documentation for more information.

update_limits!(scene::Scene, limits::Union{Automatic, Rect} = scene.limits[], padding = scene.padding[])

This function updates the limits of the Scene passed to it based on its data. If an actual limit is set by the theme or its attributes (scene.limits !== automatic), it will not update the limits. Call update_limits!(scene, automatic) for that.

vbox(scenes...; parent = Scene(clear = false), kwargs...)

save(path::String, io::VideoStream; framerate = 24)

Flushes the video stream and converts the file to the extension found in path, which can be one of the following:

• .mkv (the default, doesn't need to convert)
• .mp4 (good for Web, most supported format)
• .webm (smallest file size)
• .gif (largest file size for the same quality)

.mp4 and .mk4 are marginally bigger and .gifs are up to 6 times bigger with the same quality!

See the docs of VideoStream for how to create a VideoStream. If you want a simpler interface, consider using record.

FileIO.save(filename, scene; resolution = size(scene))

Saves a Scene to file! Allowable formats depend on the backend;

• GLMakie allows .png, .jpeg, and .bmp.
• CairoMakie allows .svg, pdf, and .jpeg.
• WGLMakie allows .png.

Resolution can be specified, via save("path", scene, resolution = (1000, 1000))!

on(f, c::Camera, nodes::Node...)

When mapping over nodes for the camera, we store them in the steering_node vector, to make it easier to disconnect the camera steering signals later!

usage @exctract scene (a, b, c, d)

usage @extractvalue scene (a, b, c, d) will become:

begin
    a = to_value(scene[:a])
    b = to_value(scene[:b])
    c = to_value(scene[:c])
    (a, b, c)
end

@get_attribute scene (a, b, c, d)

This will extract attribute a, b, c, d from scene and apply the correct attribute conversions + will extract the value if it's a signal. It will make those attributes available as variables and return them as a tuple. So the above is equal to: will become:

begin
    a = get_attribute(scene, :a)
    b = get_attribute(scene, :b)
    c = get_attribute(scene, :c)
    (a, b, c)
end

Plot Recipes in AbstractPlotting

There's two types of recipes. Type recipes define a simple mapping from a user defined type to an existing plot type. Full recipes can customize the theme and define a custom plotting function.

Type recipes

Type recipe are really simple and just overload the argument conversion pipeline. This can be done for all plot types or for a subset of plot types:

# All plot types
convert_arguments(P::Type{<:AbstractPlot}, x::MyType) = convert_arguments(P, rand(10, 10))
# Only for scatter plots
convert_arguments(P::Type{<:Scatter}, x::MyType) = convert_arguments(P, rand(10, 10))

Optionally you may define the default plot type so that plot(x::MyType) will use this:

plottype(::MyType) = Surface

Full recipes with the @recipe macro

A full recipe for MyPlot comes in two parts. First is the plot type name, arguments and theme definition which are defined using the @recipe macro. Second is a custom plot! for MyPlot, implemented in terms of the atomic plotting functions.

We use an example to show how this works:

# arguments (x, y, z) && theme are optional
@recipe(MyPlot, x, y, z) do scene
    Theme(
        plot_color => :red
    )
end

This macro expands to several things. Firstly a type definition:

const MyPlot{ArgTypes} = Combined{myplot, ArgTypes}

The type parameter of Combined contains the function instead of e.g. a symbol. This way the mapping from MyPlot to myplot is safer and simpler. (The downside is we always need a function myplot - TODO: is this a problem?)

The following signatures are defined to make MyPlot nice to use:

myplot(args...; kw_args...) = ...
myplot!(scene, args...; kw_args...) = ...
myplot(kw_args::Dict, args...) = ...
myplot!(scene, kw_args::Dict, args...) = ...
#etc (not 100% settled what signatures there will be)

A specialization of argument_names is emitted if you have an argument list (x,y,z) provided to the recipe macro:

argument_names(::Type{<: MyPlot}) = (:x, :y, :z)

This is optional but it will allow the use of plot_object[:x] to fetch the first argument from the call plot_object = myplot(rand(10), rand(10), rand(10)), for example. Alternatively you can always fetch the ith argument using plot_object[i], and if you leave out the (x,y,z), the default version of argument_names will provide plot_object[:arg1] etc.

The theme given in the body of the @recipe invocation is inserted into a specialization of default_theme which inserts the theme into any scene that plots MyPlot:

function default_theme(scene, ::MyPlot)
    Theme(
        plot_color => :red
    )
end

As the second part of defining MyPlot, you should implement the actual plotting of the MyPlot object by specializing plot!:

function plot!(plot::MyPlot)
    # normal plotting code, building on any previously defined recipes
    # or atomic plotting operations, and adding to the combined `plot`:
    lines!(plot, rand(10), color = plot[:plot_color])
    plot!(plot, plot[:x], plot[:y])
    plot
end

It's possible to add specializations here, depending on the argument types supplied to myplot. For example, to specialize the behavior of myplot(a) when a is a 3D array of floating point numbers:

const MyVolume = MyPlot{Tuple{<:AbstractArray{<: AbstractFloat, 3}}}
argument_names(::Type{<: MyVolume}) = (:volume,) # again, optional
function plot!(plot::MyVolume)
    # plot a volume with a colormap going from fully transparent to plot_color
    volume!(plot, plot[:volume], colormap = :transparent => plot[:plot_color])
    plot
end

The docstring given to the recipe will be transferred to the functions it generates.

Singleton instance to indicate that an attribute will get calculated automatically

Currently available displays by backend

Type to indicate that an attribute will get calculated automatically

A colorsampler maps numnber values from a certain range to values of a colormap

x = ColorSampler(colormap, (0.0, 1.0))
x[0.5] # returns color at half point of colormap

abstract type Transformable

This is a bit of a weird name, but all scenes and plots are transformable, so that's what they all have in common. This might be better expressed as traits.

Returns the Combined type that represents the signature of args.

apply for return type (args...,)

apply for return type PlotSpec

Each argument can be named for a certain plot type P. Falls back to arg1, arg2, etc.

Data limits calculate a minimal boundingbox from the data points in a plot. This doesn't include any transformations, markers etc.

 default_plot_signatures(funcname, funcname!, PlotType)

Creates all the different overloads for funcname that need to be supported for the plotting frontend! Since we add all these signatures to different functions, we make it reusable with this function. The Core.@__doc__ macro transfers the docstring given to the Recipe into the functions.

default_printer(v)

Prints v rounded to three digits. Here, v can be of any type accepted by round, which includes Real, Complex and many others. To use your own custom datatype it is sufficient to define Base.round(x::NewType, r::RoundingMode).

Remove combined from the current parent, and add it to a new subscene of the parent scene. Returns the new parent.

dont_touch(
    parent::GeometryPrimitive{N}, child::GeometryPrimitive{N},
    pad::Vec{N}

interpolated_getindex(cmap::AbstractArray, value::AbstractFloat, norm = (0.0, 1.0))

Like getindex, but accepts values between 0..1 and interpolates those to the full range. You can use norm, to change the range of 0..1 to whatever you want.

view = lookat(eyeposition, lookat, up) creates a view matrix with the eye located at eyeposition and looking at position lookat, with the top of the window corresponding to the direction up. Only the component of up that is perpendicular to the vector pointing from eyeposition to lookat will be used. All inputs must be supplied as 3-vectors.

mouse_in_scene(scene::Scene)

move_from_touch(
    parent::GeometryPrimitive{N, T}, child::GeometryPrimitive{N},
    pad::Vec{N}
) where {N, T}

calculates how much child rectangle needs to move to not touch the parent

Pushes an updates to all listeners of node

proj = perspectiveprojection([T], fovy, aspect, znear, zfar) defines a projection matrix with a given angular field-of-view fovy along the y-axis (measured in degrees), the specified aspect ratio, and near and far clipping planes znear, zfar. Optionally specify the element type T of the matrix.

proj = perspectiveprojection([T], rect, fov, near, far) defines the projection ratio in terms of the rectangular view size rect rather than the aspect ratio.

Fetches all plots sharing the same camera

`plot_type(plot_args...)`

The default plot type for any argument is lines. Any custom argument combination that has only one meaningful way to be plotted should overload this. e.g.:

    # make plot(rand(5, 5, 5)) plot as a volume
    plottype(x::Array{<: AbstractFlot, 3}) = Volume

plottype(P1::Type{<: Combined{T1}}, P2::Type{<: Combined{T2}})
