TwMakieHelpers

Provides customized Makie-Plots for several types.

• Density plots of Distributions
• Trace- and density plots for AbstractMCMC chains

Functionality is implemented in Package extensions. The base package only defines empty functions.

density_dist(d::UnivariateDistribution; ...)
density_dist!(ax, d::UnivariateDistribution; ...)

Plot density of univariate distribution, d. The first variant produced a figure. The second plots into given Axis.

Keyword arguments

• normalize = false: to scale y-axis to 1 for comparing densities with different spread
• prange = (0.025, 0.975): truncate x-axis to focus on main mass of the density

plot_chn(fchns::AbstractMCMC.AbstractChains; ... )
plot_chn!(fig::Figure, chns::AbstractMCMC.AbstractChains; ... )

Plot MCMCChain lines and density. The first variant produces a figure, the second variant plots into a matrix-grid of axes into given figure.

Keyword arguments

• linkaxes=false: link x-axis across density plots of several chains
• param_label="Parameter estimate": x-axis label below lowest density plot
• params = names(chns, :parameters): subset of parameters to plot
