Examples

using GLMakie
fig = Figure()
ax = LScene(fig[1, 1], show_axis=false)

x = LinRange(0, π, 50)
y = LinRange(0, 2π, 100)
z = LinRange(0, 3π, 150)

sgrid = SliderGrid(
    fig[2, 1],
    (label = "yz plane - x axis", range = 1:length(x)),
    (label = "xz plane - y axis", range = 1:length(y)),
    (label = "xy plane - z axis", range = 1:length(z)),
)

lo = sgrid.layout
nc = ncols(lo)

vol = [cos(X)*sin(Y)*sin(Z) for X ∈ x, Y ∈ y, Z ∈ z]
plt = volumeslices!(ax, x, y, z, vol)

# connect sliders to `volumeslices` update methods
sl_yz, sl_xz, sl_xy = sgrid.sliders

on(sl_yz.value) do v; plt[:update_yz][](v) end
on(sl_xz.value) do v; plt[:update_xz][](v) end
on(sl_xy.value) do v; plt[:update_xy][](v) end

set_close_to!(sl_yz, .5length(x))
set_close_to!(sl_xz, .5length(y))
set_close_to!(sl_xy, .5length(z))

# add toggles to show/hide heatmaps
hmaps = [plt[Symbol(:heatmap_, s)][] for s ∈ (:yz, :xz, :xy)]
toggles = [Toggle(lo[i, nc + 1], active = true) for i ∈ 1:length(hmaps)]

map(zip(hmaps, toggles)) do (h, t)
    connect!(h.visible, t.active)
end

Attributes

alpha

Defaults to 1.0

The alpha value of the colormap or color attribute. Multiple alphas like in plot(alpha=0.2, color=(:red, 0.5), will get multiplied.

bbox_color

Defaults to RGBAf(0.5, 0.5, 0.5, 0.5)

No docs available.

bbox_visible

Defaults to true

No docs available.

clip_planes

Defaults to automatic

Clip planes offer a way to do clipping in 3D space. You can set a Vector of up to 8 Plane3f planes here, behind which plots will be clipped (i.e. become invisible). By default clip planes are inherited from the parent plot or scene. You can remove parent clip_planes by passing Plane3f[].

colormap

Defaults to @inherit colormap :viridis

Sets the colormap that is sampled for numeric colors. PlotUtils.cgrad(...), Makie.Reverse(any_colormap) can be used as well, or any symbol from ColorBrewer or PlotUtils. To see all available color gradients, you can call Makie.available_gradients().

colorrange

Defaults to automatic

The values representing the start and end points of colormap.

colorscale

Defaults to identity

The color transform function. Can be any function, but only works well together with Colorbar for identity, log, log2, log10, sqrt, logit, Makie.pseudolog10 and Makie.Symlog10.

depth_shift

Defaults to 0.0

Adjusts the depth value of a plot after all other transformations, i.e. in clip space, where -1 <= depth <= 1. This only applies to GLMakie and WGLMakie and can be used to adjust render order (like a tunable overdraw).

fxaa

Defaults to true

Adjusts whether the plot is rendered with fxaa (anti-aliasing, GLMakie only).

highclip

Defaults to automatic

The color for any value above the colorrange.

inspectable

Defaults to @inherit inspectable

Sets whether this plot should be seen by DataInspector. The default depends on the theme of the parent scene.

inspector_clear

Defaults to automatic

Sets a callback function (inspector, plot) -> ... for cleaning up custom indicators in DataInspector.

inspector_hover

Defaults to automatic

Sets a callback function (inspector, plot, index) -> ... which replaces the default show_data methods.

inspector_label

Defaults to automatic

Sets a callback function (plot, index, position) -> string which replaces the default label generated by DataInspector.

interpolate

Defaults to false

Sets whether colors should be interpolated

lowclip

Defaults to automatic

The color for any value below the colorrange.

model

Defaults to automatic

Sets a model matrix for the plot. This overrides adjustments made with translate!, rotate! and scale!.

nan_color

Defaults to :transparent

The color for NaN values.

overdraw

Defaults to false

Controls if the plot will draw over other plots. This specifically means ignoring depth checks in GL backends

space

Defaults to :data

Sets the transformation space for box encompassing the plot. See Makie.spaces() for possible inputs.

ssao

Defaults to false

Adjusts whether the plot is rendered with ssao (screen space ambient occlusion). Note that this only makes sense in 3D plots and is only applicable with fxaa = true.

transformation

Defaults to :automatic

No docs available.

transparency

Defaults to false

Adjusts how the plot deals with transparency. In GLMakie transparency = true results in using Order Independent Transparency.

visible

Defaults to true

Controls whether the plot will be rendered or not.
