Design matrix

Setup

Package loading

using Unfold
using UnfoldMakie
using DataFrames
using CairoMakie

Data

include("../../../example_data.jl")
uf = example_data("UnfoldLinearModel")
Unfold-Type: ::UnfoldLinearModel{{Float64}} 
  Any => 1 + condition + continuous 
 
✔ model is fit.  size(coefs) (1, 45, 3)

Plot Designmatrices

The following code will result in the default configuration.

plot_designmatrix(designmatrix(uf))
Example block output

To make the design matrix easier to read, you may want to sort it using sort_data.

plot_designmatrix(designmatrix(uf); sort_data = true)
Example block output

Configurations for Design matrix plot

UnfoldMakie.plot_designmatrix — Function
plot_designmatrix!(f::Union{GridPosition, GridLayout, Figure}, data::Unfold.DesignMatrix; kwargs...)
plot_designmatrix(data::Unfold.DesignMatrix; kwargs...)

Plot a designmatrix.

Arguments

  • f::Union{GridPosition, GridLayout, Figure}
    Figure, GridLayout, or GridPosition to draw the plot.
  • data::Unfold.DesignMatrix
    Data for the plot visualization.

Keyword argumets (kwargs)

  • standardize_data::Bool = true
    Indicates whether the data is standardized by pointwise division of the data with its sampled standard deviation.
  • sort_data::Bool = true
    Indicates whether the data is sorted. It uses sortslices() of Base Julia.
  • xticks::Num = nothing
    Returns the number of labels on the x axis.
    • xticks = 0: no labels are placed.
    • xticks = 1: first possible label is placed.
    • xticks = 2: first and last possible labels are placed.
    • 2 < xticks < number of labels: equally distribute the labels.
    • xticks ≥ number of labels: all labels are placed.

Shared plot configuration options

The shared plot options can be used as follows: type = (; key = value, ...)).
For example, plot_x(...; layout = (; show_legend = true, legend_position = :right)).
Multiple defaults will be cycled until match.

Placing ; is important!

figure = NamedTuple() - use kwargs... of Makie.Figure

axis = (xlabel = "Conditions", ylabel = "Trials", xticklabelrotation = 0.39) - use kwargs... of Makie.Axis

layout = (show_legend = true, legend_position = :right, xlabelFromMapping = :x, ylabelFromMapping = :y, use_colorbar = true)

mapping = (x = (:time,), y = (:estimate, :yhat, :y))

visual = (colormap = :roma,) - use kwargs... of Makie.heatmap

legend = (orientation = :vertical, tellwidth = true, tellheight = false) - use kwargs... of Makie.Legend

colorbar = (vertical = true, tellwidth = true, tellheight = false, flipaxis = true, labelrotation = -1.5707963267948966, label = "") - use kwargs... of Makie.Colorbar

Return Value: Figure displaying the Design matrix.
