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
.
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.
colormap
= @inherit colormap :viridis
— Sets the colormap that is sampled for numeric color
s. 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).
framecolor
= :black
— No docs available.
framesize
= 1
— 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.
lowclip
= automatic
— The color for any value below the colorrange.
marker
= automatic
— No docs available.
markersize
= automatic
— 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.
Examples
using CairoMakie, 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"
