Absolute

Force transformation to be absolute, not relative to the current state. This is the default setting.

Accum

Force transformation to be relative to the current state, not absolute.

Main structure for holding attributes, for theming plots etc! Will turn all values into nodes, so that they can be updated.

Billboard attribute to always have a primitive face the camera. Can be used for rotation.

This struct provides accessible Observables to monitor the events associated with a Scene.

Fields

• window_area::Observable{GeometryBasics.HyperRectangle{2, Int64}}

  The area of the window in pixels, as a Rect2D.

• window_dpi::Observable{Float64}

  The DPI resolution of the window, as a Float64.

• window_open::Observable{Bool}

  The state of the window (open => true, closed => false).

• mousebuttons::Observable{Set{AbstractPlotting.Mouse.Button}}

  The pressed mouse buttons. Updates when a mouse button is pressed.

  See also ispressed.

• mouseposition::Observable{Tuple{Float64, Float64}}

  The position of the mouse as a NTuple{2, Float64}. Updates whenever the mouse moves.

• mousedrag::Observable{AbstractPlotting.Mouse.DragEnum}

  The state of the mouse drag, represented by an enumerator of DragEnum.

• scroll::Observable{Tuple{Float64, Float64}}

  The direction of scroll

• keyboardbuttons::Observable{Set{AbstractPlotting.Keyboard.Button}}

  See also ispressed.

• unicode_input::Observable{Vector{Char}}

• dropped_files::Observable{Vector{String}}

• hasfocus::Observable{Bool}

  Whether the Scene window is in focus or not.

• entered_window::Observable{Bool}

Unit in pixels on screen. This one is a bit tricky, since it refers to a static attribute (pixels on screen don't change) but since every visual is attached to a camera, the exact scale might change. So in the end, this is just relative to some normed camera - the value on screen, depending on the camera, will not actually sit on those pixels. Only camera that guarantees the correct mapping is the :pixel camera type.

PlotSpec{P<:AbstractPlot}(args...; kwargs...)

Object encoding positional arguments (args), a NamedTuple of attributes (kwargs) as well as plot type P of a basic plot.

Reverses the attribute T upon conversion

record(func, scene, path; framerate = 24, compression = 20)
record(func, scene, path, iter;
        framerate = 24, compression = 20, sleep = true)

The first signature provides func with a VideoStream, which it should call recordframe!(io) on when recording a frame.

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!

The compression argument controls the compression ratio; 51 is the highest compression, and 0 is the lowest (lossless).

When sleep is set to true (the default), AbstractPlotting will display the animation in real-time by sleeping in between frames. Thus, a 24-frame, 24-fps recording would take one second to record.

When it is set to false, frames are rendered as fast as the backend can render them. Thus, a 24-frame, 24-fps recording would usually take much less than one second in GLMakie.

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.

select_line(scene; kwargs...) -> line

Interactively select a line (typically an arrow) on a 2D scene by clicking the left mouse button, dragging and then un-clicking. Return an observable whose value corresponds to the selected line on the scene. In addition the function plots the line on the scene as the user clicks and moves the mouse around. When the button is not clicked any more, the plotted line disappears.

The value of the returned line is updated only when the user un-clicks and only if the selected line has non-zero length.

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

select_point(scene; kwargs...) -> point

Interactively select a point on a 2D scene by clicking the left mouse button, dragging and then un-clicking. Return an observable whose value corresponds to the selected point on the scene. In addition the function plots the point on the scene as the user clicks and moves the mouse around. When the button is not clicked any more, the plotted point disappears.

The value of the returned point is updated only when the user un-clicks.

The kwargs... are propagated into scatter! which plots the selected point.

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

Interactively select a rectangle on a 2D 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::Rect, padding = Vec3f0(0))

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

A Rect 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 Rect 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.

FileIO.save(filename, scene; resolution = size(scene), pt_per_unit = 1.0, px_per_unit = 1.0)

Save a Scene with the specified filename and format.

Supported Formats

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

Supported Keyword Arguments

All Backends

• resolution: (width::Int, height::Int) of the scene in dimensionless units (equivalent to px for GLMakie and WGLMakie).

CairoMakie

• pt_per_unit: The size of one scene unit in pt when exporting to a vector format.
• px_per_unit: The size of one scene unit in px when exporting to a bitmap format. This provides a mechanism to export the same scene with higher or lower resolution.

save(path::String, io::VideoStream; framerate = 24, compression = 20)

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!

The compression argument controls the compression ratio; 51 is the highest compression, and 0 is the lowest (lossless).

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

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

Replaces an expression with lift(argtuple -> expression, args...), where args are all expressions inside the main one that begin with $.

Example:

x = Node(rand(100)) y = Node(rand(100))

before

z = lift((x, y) -> x .+ y, x, y)

after

z = @lift(x .+ y)

You can also use parentheses around an expression if that expression evaluates to a node.

nt = (x = Node(1), y = Node(2))
@lift($(nt.x) + $(nt.y))

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
    Attributes(
        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)
    Attributes(
        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.

AbstractPatterns are image-like array types which can be used to color plottable objects. There are currently two subtypes: LinePattern and ImagePattern. Any abstract pattern must implement the to_image(pat) function, which must return a Matrix{<: AbstractRGB}.

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

https://en.wikipedia.org/wiki/Device-independent_pixel A device-independent pixel (also: density-independent pixel, dip, dp) is a physical unit of measurement based on a coordinate system held by a computer and represents an abstraction of a pixel for use by an application that an underlying system then converts to physical pixels.

FastPixel()

Use

scatter(..., marker=FastPixel())

For significant faster plotting times for large amount of points. Note, that this will draw markers always as 1 pixel.

Stepper(scene, path; format = :jpg)

Creates a Stepper for generating progressive plot examples.

Each "step" is saved as a separate file in the folder pointed to by path, and the format is customizable by format, which can be any output type your backend supports.

Glyphlayout

Stores information about the glyphs in a string that had a layout calculated for them. origins are the character origins relative to the layout's [0,0] point (the alignment) and rotation anchor). bboxes are the glyph bounding boxes relative to the glyphs' own origins. hadvances are the horizontal advance values, those are mostly needed for interactive purposes, for example to display a cursor at the right offset from a space character.

LinePattern([; kwargs...])

Creates a LinePattern for the given keyword arguments:

• direction: The direction of the line.
• width: The width of the line
• tilesize: The size of the image on which the line is drawn. This should be

compatible with the direction.

• shift: Sets the starting point for the line.
• linecolor: The color with which the line is replaced.
• background_color:: The background color.

Multiple directions, widths and shifts can also be given to create more complex patterns, e.g. a cross-hatching pattern.

Millimeter on screen. This unit respects the dimension and pixel density of the screen to represent millimeters on the screen. This is the must use unit for layouting, that needs to look the same on all kind of screens. Similar as with the Pixel unit, a camera can change the actually displayed dimensions of any object using the millimeter unit.

Main structure for holding attributes in e.g. plots!

attributes.attribute returns an observable. Since we don't actually convert all values to Observables anymore, we'll need to create new Observables on getproperty. With OnFieldUpdate, we can do that lazily, store them in listeners(onchange(obs)), and only create a new one for fields that aren't in listeners yet.

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.

_group_polys(points, ids)

Given a vector of polygon vertices, and one vector of group indices, which are assumed to be returned from the isoband algorithm, return a vector of groups, where each group has one outer polygon and zero or more inner polygons which are holes in the outer polygon. It is possible that one group has multiple outer polygons with multiple holes each.

apply for return type (args...,)

apply for return type PlotSpec

apply_scaling(value::Number, scaling::Scaling)

Scales a number to the range 0..1.

apply_transform(f, data)

Apply the data transform func to the data

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.

attributes_from(PlotType, plot)

Gets the attributes from plot, that are valid for PlotType

available_marker_symbols()

Displays all available marker symbols.

`calculated_attributes!(trait::Type{<: AbstractPlot}, plot)`

cam3d_turntable!(scene; kw_args...)

Creates a 3D camera for scene, which rotates around the plot's axis.

Checks if the linestyle format provided as a string contains only dashes and dots

Returns (N1, N2) with N1 x N2 == n. N2 might become 1

colorbuffer(scene, format::ImageStorageFormat = JuliaNative)
colorbuffer(screen, format::ImageStorageFormat = JuliaNative)

Returns the content of the given scene or screen rasterised to a Matrix of Colors. The return type is backend-dependent, but will be some form of RGB or RGBA.

• format = JuliaNative : Returns a buffer in the format of standard julia images (dims permuted and one reversed)
• format = GLNative : Returns a more efficient format buffer for GLMakie which can be directly used in FFMPEG without conversion

Returns the current active scene (the last scene that got created)

 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.

Converts the elemen array type to T1 without making a copy if the element type matches

extract_scene_attributes!(attributes)

removes all scene attributes from attributes and returns them in a new Attribute dict.

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

`plottype(plot_args...)`

Any custom argument combination that has a preferred way to be plotted should overload this. e.g.:

streamplot_impl(CallType, f, limits::Rect{N, T}, resolutionND, stepsize)

Code adapted from an example implementation by Moritz Schauer (@mschauer) from https://github.com/JuliaPlots/Makie.jl/issues/355#issuecomment-504449775

Background: The algorithm puts an arrow somewhere and extends the streamline in both directions from there. Then, it chooses a new position (from the remaining ones), repeating the the exercise until the streamline gets blocked, from which on a new starting point, the process repeats.

So, ideally, the new starting points for streamlines are not too close to current streamlines.

        ...
    end
    # attribute will get passed to convert_arguments
    # without keyword_verload, this wouldn't happen
    plot(MyType, attribute = 2)
    #You can also use the convenience macro, to overload convert_arguments in one step:
    @keywords convert_arguments(x::MyType; attribute = 1)
        ...
    end
