covellipse(μ, Σ²; kwargs...)

Plots an ellipse representing a multivariate normal distribution with mean μ and covariance matrix Σ².

Key attributes:

scale = 2: The scale factor for the ellipse size, in units of standard deviation.

vertices = 1000: The number of vertices to use for the ellipse, or a list of angular vertices.

Plot type

The plot type alias for the covellipse function is CovEllipse.

Attributes

alpha = 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 = @inherit clip_planes 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 = @inherit patchcolor — Sets the color of the poly. Can be a Vector{<:Colorant} for per vertex colors or a single Colorant. A Matrix{<:Colorant} can be used to color the mesh with a texture, which requires the mesh to contain texture coordinates. Vector or Matrices of numbers can be used as well, which will use the colormap arguments to map the numbers to colors. One can also use a <: AbstractPattern, to cover the poly with a regular pattern, e.g. for hatching.

colormap = @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 = automatic — The values representing the start and end points of colormap.

colorscale = 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, Makie.Symlog10, Makie.AsinhScale, Makie.SinhScale, Makie.LogScale, Makie.LuptonAsinhScale, and Makie.PowerScale.

cycle = [:color => :patchcolor] — Sets which attributes to cycle when creating multiple plots. The values to cycle through are defined by the parent Theme. Multiple cycled attributes can be set by passing a vector. Elements can

directly refer to a cycled attribute, e.g. :color
map a cycled attribute to a palette attribute, e.g. :linecolor => :color
map multiple cycled attributes to a palette attribute, e.g. [:linecolor, :markercolor] => :color

depth_shift = 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 = true — Adjusts whether the plot is rendered with fxaa (fast approximate anti-aliasing, GLMakie only). Note that some plots implement a better native anti-aliasing solution (scatter, text, lines). For them fxaa = true generally lowers quality. Plots that show smoothly interpolated data (e.g. image, surface) may also degrade in quality as fxaa = true can cause blurring.

highclip = automatic — The color for any value above the colorrange.

inspectable = @inherit inspectable — Sets whether this plot should be seen by DataInspector. The default depends on the theme of the parent scene.

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

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

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

joinstyle = @inherit joinstyle — Controls the rendering of outline 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 = @inherit linecap — Sets the type of line cap used for outlines. Options are :butt (flat without extrusion), :square (flat with half a linewidth extrusion) or :round.

linestyle = 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.

lowclip = automatic — The color for any value below the colorrange.

miter_limit = @inherit miter_limit — Sets the minimum inner join angle below which miter line joins truncate. See also Makie.miter_distance_to_angle.

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

nan_color = :transparent — The color for NaN values.

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

scale = 2 — Scale factor for the ellipse size, in units of standard deviation.

shading = false — Controls whether lights affect the polygon.

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

ssao = 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.

stroke_depth_shift = -1.0e-5 — Depth shift of stroke plot. This is useful to avoid z-fighting between the stroke and the fill.

strokecolor = @inherit patchstrokecolor — Sets the color of the outline around a marker.

strokecolormap = @inherit colormap — Sets the colormap that is sampled for numeric colors.

strokewidth = @inherit patchstrokewidth — Sets the width of the outline.

transformation = :automatic — Controls the inheritance or directly sets the transformations of a plot. Transformations include the transform function and model matrix as generated by translate!(...), scale!(...) and rotate!(...). They can be set directly by passing a Transformation() object or inherited from the parent plot or scene. Inheritance options include:

:automatic: Inherit transformations if the parent and child space is compatible
:inherit: Inherit transformations
:inherit_model: Inherit only model transformations
:inherit_transform_func: Inherit only the transform function
:nothing: Inherit neither, fully disconnecting the child's transformations from the parent

Another option is to pass arguments to the transform!() function which then get applied to the plot. For example transformation = (:xz, 1.0) which rotates the xy plane to the xz plane and translates by 1.0. For this inheritance defaults to :automatic but can also be set through e.g. (:nothing, (:xz, 1.0)).

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

vertices = 1000 — Number of vertices to use for the ellipse, or a list of angular vertices

visible = true — Controls whether the plot gets rendered or not.
