Hi there,

I’m tring to plot two different datasets on the same axis, the first as a blue line and the second as a red line. I have tried

```julia
plot(sol, idxs = [idx1, idx2], linecolor=[:blue,:red])

```

but instead of one line being blue and one red, both lines are a combination of both colours as seen below:

Does anyone know how to fix this?

Thank you!

You need:

```julia
linecolor=[:blue :red])

```
