Makie.spy — Function
spy(z::AbstractSparseArray) spy(x_range::NTuple{2, Number}, y_range::NTuple{2, Number}, z::AbstractSparseArray) spy(x_range::ClosedInterval, y_range::ClosedInterval, z::AbstractSparseArray)
Visualizes big sparse matrices. Usage:
using SparseArrays, GLMakie
N = 200_000
x = sprand(Float64, N, N, (3(10^6)) / (N*N));
spy(x)
# or if you want to specify the range of x and y:
spy(0..1, 0..1, x)Plot type
The plot type alias for the spy function is Spy.
Examples
using CairoMakie
using SparseArrays
N = 10 # dimension of the sparse matrix
p = 0.1 # independent probability that an entry is zero
A = sprand(N, N, p)
f, ax, plt = spy(A, framecolor = :lightgrey, axis=(;
aspect=1,
title = "Visualization of a random sparse matrix")
)
hidedecorations!(ax) # remove axis labeling
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
Per default the color of the markers will be determined by the value in the matrix, but can be overwritten via color.
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).
framecolor
Defaults to :black
By default a frame will be drawn around the data, which uses the framecolor attribute for its color.
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.
marker
Defaults to Rect
Can be any of the markers supported by scatter!. Note, for huge sparse arrays, one should use FastPixel, which is a very fast, but can only render square markers. So, without Axis(...; aspect=1), the markers won’t have the correct size. Compare:
data = sprand(10, 10, 0.5)
f = Figure()
spy(f[1, 1], data; marker=FastPixel())
spy(f[1, 2], data; marker=FastPixel(), axis=(; aspect=1))
fmarker_gap
Defaults to 0
Makes the marker size smaller to create a gap between the markers. The unit of this is in data space.
markersize
Defaults to automatic
markersize=automatic, will make the marker size fit the data - but can also be set manually.
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.
