Shared plot configuration options

The shared plot options can be used as follows: type = (; key = value, ...)).
For example, plot_x(...; colorbar = (; vertical = true, label = "Test")).
Multiple defaults will be cycled until match.

Placing ; is important!

axis = NamedTuple() - use kwargs... of Makie.Axis

layout = (show_legend = true, use_colorbar = true) - check this page

legend = (orientation = :vertical, tellwidth = true, tellheight = false, halign = :right, valign = :center, title = "Splines", framevisible = false) - use kwargs... of Makie.Legend

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

plot_topoplotseries(f::Union{GridPosition, GridLayout, Figure}, data::Union{<:Observable{<:DataFrame},DataFrame}; kwargs...)
plot_topoplotseries!(data::Union{<:Observable{<:DataFrame},DataFrame}; kwargs...)

Multiple miniature topoplots in regular distances.

Arguments

• f::Union{GridPosition, GridLayout, GridLayoutBase.GridSubposition, Figure}
Figure, GridLayout, GridPosition, or GridLayoutBase.GridSubposition to draw the plot.
• data::Union{<:Observable{<:DataFrame},DataFrame}
  DataFrame with data or Observable DataFrame.
  Requires a time column by default, but can be overridden by specifying mapping=(; x=:my_column) with any continuous or categorical column.

Keyword arguments (kwargs)

• bin_width::Real = nothing
  Number specifing the width of bin of continuous x-value in its units.
  
• bin_num::Real = nothing
  Number of topoplots.
  Either bin_width, or bin_num should be specified. Error if they are both specified
  If mapping.col or mapping.row are categorical bin_width and bin_num stay as nothing.
• combinefun::Function = mean
  Specify how the samples within bin_width are summarised.
  Example functions: mean, median, std.
• rasterize_heatmaps::Bool = true
  Force rasterization of the plot heatmap when saving in svg format.
  Except for the interpolated heatmap, all lines/points are vectors.
  This is typically what you want, otherwise you get ~128x128 vectors per topoplot, which makes everything very slow.
• col_labels::Bool, row_labels::Bool = true
  Shows column and row labels for categorical values.
• positions::Vector{Point{2, Float32}} = nothing
  Specify channel positions. Requires the list of x and y positions for all unique electrodes.
• labels::Vector{String} = nothing
  Show labels for each electrode.
• interactive_scatter = nothing
  Enable interactive mode.
  If you create obs_tuple = Observable((0, 0, 0)) and pass it into interactive_scatter you can update the observable tuple with the indices of the clicked topoplot markers.
  (0, 0, 0) corresponds to the (row of topoplot layout, column of topoplot layout, electrode).
• topo_axis::NamedTuple = (;)
  Here you can flexibly change configurations of topoplots.
  To see all options just type ?Axis in REPL.
• mapping = (; col = :time, row = nothing, layout = nothing)
  mapping.col - specify x-value, can be any continuous or categorical variable.
  mapping.row - specify y-value, can be any continuous or categorical variable (not implemented yet).
  mapping.layout - arranges topoplots by rows when equals :time.
  
• visual.colorrange::2-element Vector{Int64}
  Resposnible for colorrange in topoplots and in colorbar.
• topo_attributes::NamedTuple = (;)
  Here you can flexibly change configurations of the topoplot interoplation.
  To see all options just type ?Topoplot.topoplot in REPL.
  Defaults: interp_resolution = (128, 128), interpolation = CloughTocher()

rel_to_abs_bbox(org, rel)

Takes a rectangle org consiting of coordinates of origins and applies the relative transformation tuple rel.

Return Value: Makie.BBox.

supportive_defaults(cfg_symb::Symbol)

Default configurations for the supporting axis. Similar to PlotConfig, but these configurations are not shared by all plots.
Such supporting axes allow users to flexibly see defaults in docstrings and manipulate them using corresponding axes.

For developers: to make them updateable in the function, use update_axis. Return value: NamedTuple.

to_positions(x, y, z; sphere = [0, 0, 0.])
to_positions(pos::AbstractMatrix; sphere = [0, 0, 0.])

Projects 3D electrode positions to a 2D layout. Reimplementation of the MNE algorithm.

Assumes size(pos) = (3, nChannels) when input is AbstractMatrix.

Tip: You can get positions directly from an MNE object after loading PyMNE and enabling the UnfoldMakie PyMNE extension.

Return Value: Vector{Point2{Float64}}.

update_axis(support_axis::NamedTuple; kwargs...)

Update values of NamedTuple{key = value}.
Used for supportive axes to make users be able to flexibly change them.

PlotConfig(<plotname>)

Contains several different fields that can modify various aspects of the plot.

PCPTicks

Used to inject extrema ticks and round them if necessary.
