contour

contour(x, y, z)
contour(z::Matrix)

Creates a contour plot of the plane spanning x::Vector, y::Vector, z::Matrix. If only z::Matrix is supplied, the indices of the elements in z will be used as the x and y locations when plotting the contour.

Plot type

The plot type alias for the contour function is Contour.

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 = nothing — The color of the contour lines. If nothing, the color is determined by the numerical values of the contour levels in combination with colormap and colorrange.

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.

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).

enable_depth = true — No docs available.

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 joinstyle — No docs available.

labelcolor = nothing — Color of the contour labels, if nothing it matches color by default.

labelfont = @inherit font — The font of the contour labels.

labelformatter = contour_label_formatter — Formats the numeric values of the contour levels to strings.

labels = false — If true, adds text labels to the contour lines.

labelsize = 10 — Font size of the contour labels

levels = 5 — Controls the number and location of the contour lines. Can be either

• an Int that produces n equally wide levels or bands

• an AbstractVector{<:Real} that lists n consecutive edges from low to high, which result in n-1 levels or bands

linecap = @inherit linecap — No docs available.

linestyle = nothing — No docs available.

linewidth = 1.0 — No docs available.

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

miter_limit = @inherit miter_limit — No 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

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.
