Appearance

arc ​

Makie.arc Function
julia
arc(origin, radius, start_angle, stop_angle; kwargs...)

This function plots a circular arc, centered at origin with radius radius, from start_angle to stop_angle. origin must be a coordinate in 2 dimensions (i.e., a Point2); the rest of the arguments must be <: Number.

Examples:

arc(Point2f(0), 1, 0.0, π) arc(Point2f(1, 2), 0.3, π, -π)

Plot type

The plot type alias for the arc function is Arc.

Examples ​

julia
using CairoMakie
arc(Point2f(0), 1, -π, π)
julia
using CairoMakie
f = Figure()
Axis(f[1, 1])

for i in 1:10
    arc!(Point2f(0, i), i, -π, π)
end

f
julia
using CairoMakie
f = Figure()
Axis(f[1, 1])

for i in 1:4
    radius = 1/(i*2)
    left = 1/(i*2)
    right = (i*2-1)/(i*2)
    arc!(Point2f(left, 0), radius, 0, π)
    arc!(Point2f(right, 0), radius, 0, π)
end
for i in 3:4
    radius = 1/(i*(i-1)*2)
    left = (1/i) + 1/(i*(i-1)*2)
    right = ((i-1)/i) - 1/(i*(i-1)*2)
    arc!(Point2f(left, 0), radius, 0, π)
    arc!(Point2f(right, 0), radius, 0, π)
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.

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 linecolor

The color of the line.

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]

Sets which attributes to cycle when creating multiple plots.

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).

fxaa ​

Defaults to false

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 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.

joinstyle ​

Defaults to @inherit joinstyle

Controls the rendering at corners. Options are :miter for sharp corners, :bevel for "cut off" corners, and :round for rounded corners. If the corner angle is below miter_limit, :miter is equivalent to :bevel to avoid long spikes.

linecap ​

Defaults to @inherit linecap

Sets the type of line cap used. Options are :butt (flat without extrusion), :square (flat with half a linewidth extrusion) or :round.

linestyle ​

Defaults to nothing

Sets the dash pattern of the line. Options are :solid (equivalent to nothing), :dot, :dash, :dashdot and :dashdotdot. These can also be given in a tuple with a gap style modifier, either :normal, :dense or :loose. For example, (:dot, :loose) or (:dashdot, :dense).

For custom patterns have a look at Makie.Linestyle.

linewidth ​

Defaults to @inherit linewidth

Sets the width of the line in screen units

lowclip ​

Defaults to automatic

The color for any value below the colorrange.

miter_limit ​

Defaults to @inherit miter_limit

Sets the minimum inner join angle below which miter joins truncate. See also Makie.miter_distance_to_angle.

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

resolution ​

Defaults to 361

The number of line points approximating the arc.

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.
