Hi there,

I have a DiffrentialEquations.jl solution from a model I created using ModelingToolkit.jl where u has a number of different columns.

Is there a way of displaying the results of just the columns of a specified index? I know you can plot only specific indexes like this

```julia
plot(sol, idxs = [model.component.parameter])

```

but I would like to be able to just look at the actual numbers instead of a plot, and have the possibility to store the values from this one index in a separate variable.

I hope this explains my problem.

Thanks!

`sol[model.component.parameter]`?
