Plotting

Plotting lives in a package extension that is loaded together with a Makie backend: using GLMakie for the interactive viewer, using CairoMakie for static figures (the core package does not depend on Makie).

Trajectories

plot_trajectory draws a Trajectory segment by segment onto a Makie Axis, with one LineStyle for all modes or a Dict{Symbol, LineStyle} with one style per mode name:

using MappyDS, CairoMakie

traj = trajectory(pmap, -3.0, params; n = 5)
ax = plot_trajectory(traj; styles = Dict(:A => LineStyle(; color = :teal, alpha = 0.8)))
save("izhikevich.png", ax.parent)

Iterating a map interactively

plot2d iterates a map and draws its orbit: each frame computes one iteration from the current state and draws the trajectory segments and the image point. With GLMakie the figure keeps iterating and reacts to the user (click to restart from the clicked point, f to toggle the trajectories, space to clear, p to select a parameter and up/down to change it):

using MappyDS, GLMakie

config = PlotConfig(;
    xlim = (-60.0, 40.0), ylim = (-10.0, 5.0), xlabel = "v", ylabel = "u",
    param_keys = [:a, :I], param_step = 0.1,
    trajectory_style = Dict(:A => LineStyle(; color = :teal, alpha = 0.5)),
)
plot2d(pmap, -3.0, params, config)

With frames = n the figure is built from n iterations and returned, which is the way to produce a picture with CairoMakie:

using CairoMakie
fig = plot2d(henon_map, [0.1, 0.1], (a = 1.4, b = 0.3), PlotConfig(; xlim = (-2.0, 2.0), ylim = (-0.5, 0.5), only_map = true); frames = 2000, show = false)
save("henon.png", fig)
