MakieCore.poly — Function
poly(vertices, indices; kwargs...)
poly(points; kwargs...)
poly(shape; kwargs...)
poly(mesh; kwargs...)Plots a polygon based on the arguments given. When vertices and indices are given, it functions similarly to mesh. When points are given, it draws one polygon that connects all the points in order. When a shape is given (essentially anything decomposable by GeometryBasics), it will plot decompose(shape).
poly(coordinates, connectivity; kwargs...)
Plots polygons, which are defined by coordinates (the coordinates of the vertices) and connectivity (the edges between the vertices).
Plot type
The plot type alias for the poly function is Poly.

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 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
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().
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 0 <= depth <= 1. This only applies to GLMakie and WGLMakie and can be used to adjust render order (like a tunable overdraw).
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.
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.
model
Defaults to automatic
Sets a model matrix for the plot. This overrides adjustments made with translate!, rotate! and scale!.
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.
stroke_depth_shift
Defaults to -1.0e-5
Depth shift of stroke plot. This is useful to avoid z-fighting between the stroke and the fill.
