I have computed `sol`

from DifferentialEquations, and need to transform selected values before plotting them. Specifically, I want to convert values from fraction to percentage (`f2p`

).

Suppose I want transform a single variable, say variable nr. `2`

. I can do that by:

```
f2p = (t,x) -> (t,100x)
plot(sol,vars=(f2p,0,2))
```

Next, suppose I want to plot variable nr. `1`

, `2`

, and `4`

:

```
plot(sol,vars=(0,[1,2,4]))
```

Question:

- Is there a way to use the same mapping to percentage on variables
`1`

,`2`

,`4`

in a single plot command?

The following does *not* work:

```
plot(sol, vars=(f2p,0,[1,2,4]))
```

Is there a way to do this without doing it the “hard” way:

```
plot(sol, vars=(f2p,0,1))
plot!(sol, vars=(f2p,0,2))
plot!(sol, vars=(f2p,0,3))
```

?
