fig

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.

bar_labels

Defaults to nothing

Labels added at the end of each bar.

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[].

color

Defaults to @inherit patchcolor

No docs available.

color_over_background

Defaults to automatic

No docs available.

color_over_bar

Defaults to automatic

No docs available.

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.

cycle

Defaults to [:color => :patchcolor]

No docs available.

depth_shift

Defaults to 0.0

adjusts the depth value of a plot after all other transformations, i.e. in clip space, where 0 <= depth <= 1. This only applies to GLMakie and WGLMakie and can be used to adjust render order (like a tunable overdraw).

direction

Defaults to :y

Controls the direction of the bars, can be :y (vertical) or :x (horizontal).

dodge

Defaults to automatic

No docs available.

dodge_gap

Defaults to 0.03

No docs available.

fillto

Defaults to automatic

Controls the baseline of the bars. This is zero in the default automatic case unless the barplot is in a log-scaled Axis. With a log scale, the automatic default is half the minimum value because zero is an invalid value for a log scale.

flip_labels_at

Defaults to Inf

No docs available.

fxaa

Defaults to true

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

gap

Defaults to 0.2

The final width of the bars is calculated as w * (1 - gap) where w is the width of each bar as determined with the width attribute.

highclip

Defaults to automatic

The color for any value above the colorrange.

inspectable

Defaults to true

sets whether this plot should be seen by DataInspector.

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.

label_align

Defaults to automatic

No docs available.

label_color

Defaults to @inherit textcolor

No docs available.

label_font

Defaults to @inherit font

The font of the bar labels.

label_formatter

Defaults to bar_label_formatter

No docs available.

label_offset

Defaults to 5

The distance of the labels from the bar ends in screen units. Does not apply when label_position = :center.

label_position

Defaults to :end

The position of each bar's label relative to the bar. Possible values are :end or :center.

label_rotation

Defaults to

No docs available.

label_size

Defaults to @inherit fontsize

The font size of the bar labels.

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!.

n_dodge

Defaults to automatic

No docs available.

nan_color

Defaults to :transparent

The color for NaN values.

offset

Defaults to 0.0

No docs available.

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.

stack

Defaults to automatic

No docs available.

strokecolor

Defaults to @inherit patchstrokecolor

No docs available.

strokewidth

Defaults to @inherit patchstrokewidth

No docs available.

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.

width

Defaults to automatic

The gapless width of the bars. If automatic, the width w is calculated as minimum(diff(sort(unique(positions))). The actual width of the bars is calculated as w * (1 - gap).
