"Computer Modern" not global default font

[oameye]

The solution to issue #49:
HarmonicBalance does not define "Computer Modern" is the the global default font. Yet only the HarmonicBalance plot functions will use Computer modern by "default".

I tested the code with the Duffing oscillator example:

using HarmonicBalance
@variables α, ω, ω0, F, t, γ, x(t) # declare constant variables and a function x(t)
diff_eq = DifferentialEquation(d(x,t,2) + ω0^2*x + α*x^3 + γ*d(x,t) ~ F*cos(ω*t), x) #declare differential equation
add_harmonic!(diff_eq, x, ω) # specify the ansatz x = u(T) cos(ωt) + v(T) sin(ωt)
harmonic_eq = get_harmonic_equations(diff_eq)
varied = ω => LinRange(0.9, 1.2, 100) # range of parameter values
fixed = (α => 1., ω0 => 1.0, F => 0.01, γ=>0.01) # fixed parameters
solutions = get_steady_states(harmonic_eq, varied, fixed)
plot(solutions, x="ω", y="sqrt(u1^2 + v1^2)")
plot_phase_diagram(solutions)

x = -5:0.1:5
plot(x, x.^2)

This should work but the point of set_Plots_default was to avoid this duplicity scattered around and have everything in one place.

Could you try passing it via a Dict ? Instead of set_Plots_default, we could have a
_default_Plots = Dict([:tickfont => "Computer Modern", ...) etc.

Then prepending this to the plotting functions such as
plot(res, varargs... ; _default_Plots... , kwargs...) should do the trick. plot1D and plot2D receive it from plot afaik

This also needs to be added to TimeEvolution.plot

The default font is now implemented by a Dictionary, like you suggsted. It is again tested with the Duffing oscillator example (see above). I added the dictionary to all plot occurences I could find, e.g., in the modules.

Great, one more thing: within the modules (TimeEvolution, LinearResponse), you need to call HarmonicBalance._set_Plots_default to refer back to the main scope (now these won't plot).

reminds me we should have automated tests for plotting, even to see if the functions don't error :))

Ha yes rookie mistake. Will do it in the afternoon.
