在Julia中，在同一图形上绘制多个ODE解决方案的最佳方法是什么？

using Plots
using DifferentialEquations

function solve_ode(eq, initial_condition)
    # 使用ODE求解器求解ODE方程
    # ...
    return solution
end

# 定义多个ODE解决方案
solutions = []

# 解决方案1
eq1 = @ode_def begin
    dy = y
end
initial_condition1 = [1.0]
push!(solutions, solve_ode(eq1, initial_condition1))

# 解决方案2
eq2 = @ode_def begin
    dy = -y
end
initial_condition2 = [2.0]
push!(solutions, solve_ode(eq2, initial_condition2))

# 绘制图形
plot()
for solution in solutions
    plot!(solution, xlabel="Time", ylabel="Value")
end
display(plot!)
