There are some examples here in discourse. See if [this](https://discourse.julialang.org/t/argument-for-number-of-axis-ticks/76817/2) one helps.

With the latest recommended Format.jl package, try:

```julia-auto
using Format, Plots
x = 0:1:10
plot(x, x*1e-6, yformatter = x -> cfmt( "%.1e", x), tickfontsize=6)

```
