interactive_evolution's idxs parameter doesn't behave as expected #96

Open perryprog opened 2 years ago

perryprog commented 2 years ago

When using interactive_evolution (and possibly other function that support idxs; I haven't tested them), the idxs parameter doesn't seem to behave correctly. When using DynamicalSystem's double pendulum system (param order is [θ₁,ω₁,θ₂,ω₂]) and attempting to graph both theta values, this is what I get:

julia> using GLMakie, DynamicalSystems, InteractiveDynamics

julia> ds = Systems.double_pendulum()
4-dimensional continuous dynamical system
 state:       [1.5708, 0.0, 0.0, 0.5]
 rule f:      doublependulum_rule
 in-place?    false
 jacobian:    ForwardDiff
 parameters:  [10.0, 1.0, 1.0, 1.0, 1.0]

julia> interactive_evolution(ds; idxs = [1, 3]);

If I attempt to use a tuple for idxs instead, as sometimes suggested by the documentation (I assume either an Array or a Tuple is supposed to be fine), I get this type error:

Facing the same problem with the lorenz attractor GUI. Is there any update?

no updates yet but this is super easy to fix if someone wants to do a pr
