Axis3

Attributes

alignmode

Defaults to Inside()

The alignment of the scene in its suggested bounding box.

aspect

Defaults to (1.0, 1.0, 2 / 3)

Controls the lengths of the three axes relative to each other.

Options are:

• A three-tuple of numbers, which sets the relative lengths of the x, y and z axes directly

• :data which sets the length ratios equal to the limit ratios of the axes. This results in an "unsquished" look where a cube in data space looks like a cube and not a cuboid.

• :equal which is a shorthand for (1, 1, 1)

using CairoMakie
fig = Figure()

Axis3(fig[1, 1], aspect = (1, 1, 1), title = "aspect = (1, 1, 1)")
Axis3(fig[1, 2], aspect = (2, 1, 1), title = "aspect = (2, 1, 1)")
Axis3(fig[2, 1], aspect = (1, 2, 1), title = "aspect = (1, 2, 1)")
Axis3(fig[2, 2], aspect = (1, 1, 2), title = "aspect = (1, 1, 2)")

fig

using CairoMakie
using FileIO

fig = Figure()

brain = load(assetpath("brain.stl"))

ax1 = Axis3(fig[1, 1], aspect = :equal, title = "aspect = :equal")
ax2 = Axis3(fig[1, 2], aspect = :data, title = "aspect = :data")

for ax in [ax1, ax2]
    mesh!(ax, brain, color = :gray80)
end

fig

azimuth

Defaults to 1.275pi

The azimuth (left / right) angle of the camera.

At azimuth = 0, the camera looks at the axis from a point on the positive x axis, and rotates to the right from there with increasing values. At the default value 1.275π, the x axis goes to the right and the y axis to the left.

using CairoMakie
fig = Figure()

for (i, azimuth) in enumerate([0, 0.1, 0.2, 0.3, 0.4, 0.5])
    Axis3(fig[fldmod1(i, 3)...], azimuth = azimuth * pi,
        title = "azimuth = $(azimuth)π", viewmode = :fit)
end

fig

backgroundcolor

Defaults to :transparent

The background color

dim1_conversion

Defaults to nothing

Global state for the x dimension conversion.

dim2_conversion

Defaults to nothing

Global state for the y dimension conversion.

dim3_conversion

Defaults to nothing

Global state for the z dimension conversion.

elevation

Defaults to pi / 8

The elevation (up / down) angle of the camera. Possible values are between -pi/2 (looking from the bottom up) and +pi/2 (looking from the top down).

using CairoMakie
fig = Figure()

for (i, elevation) in enumerate([0, 0.05, 0.1, 0.15, 0.2, 0.25])
    Axis3(fig[fldmod1(i, 3)...], elevation = elevation * pi,
        title = "elevation = $(elevation)π", viewmode = :fit)
end

fig

halign

Defaults to :center

The horizontal alignment of the scene in its suggested bounding box.

height

Defaults to nothing

The height setting of the scene.

limits

Defaults to (nothing, nothing, nothing)

The limits that the user has manually set. They are reinstated when calling reset_limits! and are set to nothing by autolimits!. Can be either a tuple (xlow, xhigh, ylow, yhigh, zlow, zhigh) or a tuple (nothing_or_xlims, nothing_or_ylims, nothing_or_zlims). Are set by xlims!, ylims!, zlims! and limits!.

perspectiveness

Defaults to 0.0

This setting offers a simple scale from 0 to 1, where 0 looks like an orthographic projection (no perspective) and 1 is a strong perspective look. For most data visualization applications, perspective should be avoided because it makes interpreting the data correctly harder. It can be of use, however, if aesthetics are more important than neutral presentation.

using CairoMakie
fig = Figure()

for (i, perspectiveness) in enumerate(range(0, 1, length = 6))
    ax = Axis3(fig[fldmod1(i, 3)...]; perspectiveness, protrusions = (0, 0, 0, 15),
        title = ":perspectiveness = $(perspectiveness)")
    hidedecorations!(ax)
end

fig

protrusions

Defaults to 30

The protrusions control how much gap space is reserved for labels etc. on the sides of the Axis3. Unlike Axis, Axis3 currently does not set these values automatically depending on the properties of ticks and labels. This is because the effective protrusions also depend on the rotation and scaling of the axis cuboid, which changes whenever the Axis3 shifts in the layout. Therefore, auto-updating protrusions could lead to an endless layout update cycle.

The default value of 30 for all sides is just a heuristic and might lead to collisions of axis decorations with the Figure boundary or other plot elements. If that's the case, you can try increasing the value(s).

The protrusions attribute accepts a single number for all sides, or a tuple of (left, right, bottom, top).

using CairoMakie
    fig = Figure(backgroundcolor = :gray97)
    Box(fig[1, 1], strokewidth = 0) # visualizes the layout cell
    Axis3(fig[1, 1], protrusions = 100, viewmode = :stretch,
        title = "protrusions = 100")
    fig

using CairoMakie
    fig = Figure(backgroundcolor = :gray97)
    Box(fig[1, 1], strokewidth = 0) # visualizes the layout cell
    ax = Axis3(fig[1, 1], protrusions = (0, 0, 0, 20), viewmode = :stretch,
        title = "protrusions = (0, 0, 0, 20)")
    hidedecorations!(ax)
    fig

targetlimits

Defaults to Rect3f(Vec3f(0, 0, 0), Vec3f(1, 1, 1))

The limits that the axis tries to set given other constraints like aspect. Don't set this directly, use xlims!, ylims! or limits! instead.

tellheight

Defaults to true

Controls if the parent layout can adjust to this element's height

tellwidth

Defaults to true

Controls if the parent layout can adjust to this element's width

title

Defaults to ""

The axis title string.

titlealign

Defaults to :center

The horizontal alignment of the title.

titlecolor

Defaults to @inherit :textcolor :black

The color of the title

titlefont

Defaults to :bold

The font family of the title.

titlegap

Defaults to 4.0

The gap between axis and title.

titlesize

Defaults to @inherit :fontsize 16.0f0

The title's font size.

titlevisible

Defaults to true

Controls if the title is visible.

valign

Defaults to :center

The vertical alignment of the scene in its suggested bounding box.

viewmode

Defaults to :fitzoom

The view mode affects the final projection of the axis by fitting the axis cuboid into the available space in different ways.

• :fit uses a fixed scaling such that a tight sphere around the cuboid touches the frame edge. This means that the scaling doesn't change when rotating the axis (the apparent size of the axis stays the same), but not all available space is used. The chosen aspect is maintained using this setting.

• :fitzoom uses a variable scaling such that the closest cuboid corner touches the frame edge. When rotating the axis, the apparent size of the axis changes which can result in a "pumping" visual effect. The chosen aspect is also maintained using this setting.

• :stretch pulls the cuboid corners to the frame edges such that the available space is filled completely. The chosen aspect is not maintained using this setting, so :stretch should not be used if a particular aspect is needed.

using CairoMakie
fig = Figure()

for (i, viewmode) in enumerate([:fit, :fitzoom, :stretch])
    for (j, elevation) in enumerate([0.1, 0.2, 0.3] .* pi)

        Label(fig[i, 1:3, Top()], "viewmode = $(repr(viewmode))", font = :bold)

        # show the extent of each cell using a box
        Box(fig[i, j], strokewidth = 0, color = :gray95)

        ax = Axis3(fig[i, j]; viewmode, elevation, protrusions = 0, aspect = :equal)
        hidedecorations!(ax)
