When using `Plots.jl`, is there a straightforward way to plot on log scale with data which might contain zeros? When using `matplotlib` in Python, these values are just filtered and an image is still rendered, but `Plots.jl` throws an error. Do I just have to manually filter those values out?

I thought this was partly fixed, test case:

```julia
using Plots
plot(cumsum(randn(1000,4), dims=1), yaxis=(:log10, [0.1, :auto]))

```

If you don’t specify `ylims` then it gets confused. (Ref: [this issue?](https://github.com/JuliaPlots/Plots.jl/issues/1959))

[https://github.com/JuliaPlots/Plots.jl/pull/2962](https://github.com/JuliaPlots/Plots.jl/pull/2962) that issue should be fixed now

Yes, as soon as i specify the limits in that way, it works fine.
