linesegments

linesegments(positions)
linesegments(vector_of_2tuples_of_points)
linesegments(x, y)
linesegments(x, y, z)

Plots a line for each pair of points in (x, y, z), (x, y), or positions.

Plot type

The plot type alias for the linesegments function is LineSegments.

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 linecolor — The color of the line.

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] — Sets which attributes to cycle when creating multiple plots.

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 = false — 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.

linecap = @inherit linecap — Sets the type of linecap used, i.e. :butt (flat with no extrusion), :square (flat with 1 linewidth extrusion) or :round.

linestyle = nothing — Sets the pattern of the line e.g. :solid, :dot, :dashdot. For custom patterns look at Linestyle(Number[...])

linewidth = @inherit linewidth — Sets the width of the line in pixel units

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

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

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.

transformation = automatic — No 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.

Examples

using CairoMakie


f = Figure()
Axis(f[1, 1])

xs = 1:0.2:10
ys = sin.(xs)

linesegments!(xs, ys)
linesegments!(xs, ys .- 1, linewidth = 5)
linesegments!(xs, ys .- 2, linewidth = 5, color = LinRange(1, 5, length(xs)))

Dealing with outline artifacts in GLMakie

In GLMakie 3D line plots can generate outline artifacts depending on the order line segments are rendered in. Currently there are a few ways to mitigate this problem, but they all come at a cost:

fxaa = true will disable the native anti-aliasing of line segments and use fxaa instead. This results in less detailed lines.
transparency = true will disable depth testing to a degree, resulting in all lines being rendered without artifacts. However with this lines will always have some level of transparency.
overdraw = true will disable depth testing entirely (read and write) for the plot, removing artifacts. This will however change the z-order of line segments and allow plots rendered later to show up on top of the linesegments plot.

using GLMakie

ps = rand(Point3f, 500)
cs = rand(500)
f = Figure(size = (600, 650))
Label(f[1, 1], "base", tellwidth = false)
linesegments(f[2, 1], ps, color = cs, fxaa = false)
Label(f[1, 2], "fxaa = true", tellwidth = false)
linesegments(f[2, 2], ps, color = cs, fxaa = true)
Label(f[3, 1], "transparency = true", tellwidth = false)
linesegments(f[4, 1], ps, color = cs, transparency = true)
Label(f[3, 2], "overdraw = true", tellwidth = false)
linesegments(f[4, 2], ps, color = cs, overdraw = true)
