poly

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 = 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.

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 Makie.LinePattern, to cover the poly with a regular stroke pattern.

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 and Makie.Symlog10.

cycle = [:color => :patchcolor]No docs available.

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

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

inspectable = true — sets whether this plot should be seen by DataInspector.

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 joinstyleNo docs available.

linecap = @inherit linecapNo docs available.

linestyle = nothing — Sets the pattern of the line (e.g. :solid, :dot, :dashdot)

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

miter_limit = @inherit miter_limitNo docs available.

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

shading = NoShadingNo docs available.

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.

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 = automaticNo docs available.

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

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