spy
spy(x::Range, y::Range, z::AbstractSparseArray)
Visualizes big sparse matrices. Usage:
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 = 100 # 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, markersize = 4, marker = :circle, framecolor = :lightgrey)
hidedecorations!(ax) # remove axis labeling
ax.title = "Visualization of a random sparse matrix"
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.
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).
framecolor
Defaults to :black
No docs available.
framesize
Defaults to 1
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.
lowclip
Defaults to automatic
The color for any value below the colorrange.
marker
Defaults to automatic
No docs available.
markersize
Defaults to automatic
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.
