contour
Makie.contour Function
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.
Examples
using CairoMakie
f = Figure()
Axis(f[1, 1])
xs = LinRange(0, 10, 100)
ys = LinRange(0, 15, 100)
zs = [cos(x) * sin(y) for x in xs, y in ys]
contour!(xs, ys, zs)
f
Omitting the xs and ys results in the indices of zs being used. We can also set arbitrary contour-levels using levels
using CairoMakie
f = Figure()
Axis(f[1, 1])
xs = LinRange(0, 10, 100)
ys = LinRange(0, 15, 100)
zs = [cos(x) * sin(y) for x in xs, y in ys]
contour!(zs,levels=-1:0.1:1)
f
One can also add labels and control label attributes such as labelsize, labelcolor or labelfont.
using CairoMakie
himmelblau(x, y) = (x^2 + y - 11)^2 + (x + y^2 - 7)^2
x = y = range(-6, 6; length=100)
z = himmelblau.(x, y')
levels = 10.0.^range(0.3, 3.5; length=10)
colorscale = ReversibleScale(x -> x^(1 / 10), x -> x^10)
f, ax, ct = contour(x, y, z; labels=true, levels, colormap=:hsv, colorscale)
f
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 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
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().
colorrange
Defaults to automatic
The values representing the start and end points of colormap.
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).
enable_depth
Defaults to true
No docs available.
fxaa
Defaults to true
adjusts whether the plot is rendered with fxaa (anti-aliasing, GLMakie only).
highclip
Defaults to automatic
The color for any value above the colorrange.
inspectable
Defaults to true
sets whether this plot should be seen by DataInspector.
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.
joinstyle
Defaults to @inherit joinstyle
No docs available.
labelcolor
Defaults to nothing
Color of the contour labels, if nothing it matches color by default.
labelfont
Defaults to @inherit font
The font of the contour labels.
labelformatter
Defaults to contour_label_formatter
Formats the numeric values of the contour levels to strings.
labels
Defaults to false
If true, adds text labels to the contour lines.
labelsize
Defaults to 10
Font size of the contour labels
levels
Defaults to 5
Controls the number and location of the contour lines. Can be either
an
Intthat produces n equally wide levels or bandsan
AbstractVector{<:Real}that lists n consecutive edges from low to high, which result in n-1 levels or bands
linecap
Defaults to @inherit linecap
No docs available.
linestyle
Defaults to nothing
No docs available.
linewidth
Defaults to 1.0
No docs available.
lowclip
Defaults to automatic
The color for any value below the colorrange.
miter_limit
Defaults to @inherit miter_limit
No docs available.
model
Defaults to automatic
Sets a model matrix for the plot. This overrides adjustments made with translate!, rotate! and scale!.
nan_color
Defaults to :transparent
The color for NaN values.
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.
transformation
Defaults to automatic
No docs available.
transparency
Defaults to false
Adjusts how the plot deals with transparency. In GLMakie transparency = true results in using Order Independent Transparency.
visible
Defaults to true
Controls whether the plot will be rendered or not.
