Hello,
I am looking for an efficient way to change the label from
to something like
> operation1
> operation2
> operation3
> …
but not with the manual labeling as bellow. Because for a more number of operations it seems not very efficient!
```julia
using StatsPlots;
plot!(label = ["operation1" "operation2" "operation3" ...])
```
Does anyone have an idea? Thanks.

A comprehension does it:
```julia
label = ["operation$j" for j = 1 : n]
```

thank you, I already tried that but it looks like this:
what am I doing wrong?

Apologies - I forgot that legends use 1xn arrays rather than nx1 vectors. This always trips me up. There is probably a nice one-liner that uses a comprehension to make a 1xn Matrix, but I don’t know the way. But a loop is easy.

What I do in practice is have a little function that makes sure a legend is a Matrix. It passes 1xn matrices through without change, but makes vectors into matrices. So I just call `label = make_legend(lbls)` each time and don’t have to worry about whether I had a vector or matrix of labels.

```julia
label = ["operation$j" for j = (1:8)']
```
You need an 1xn matrix

Perfect! 👍
It works exactly the way I want, thank you.
