iterate_plot_pos(a::Int64, b::Int64)

Iterate the positions in a Figure, so that there are no gaps and the number of rows is never more than the number of columns.

push!(list_obs::Observable{Vector{T}}, value::T) where {T<:Real}

Push number onto a Vector packaged in the given Observable and trigger Observable.

push!(obs::Observable{Vector{Datapoint}}, dp::Datapoint)

Push Datapoint onto a Vector packaged in the given Observable and trigger Observable.

append!(obs::Observable{Vector{T}}, val_vector::Vector{T}) where {T<:Real}
