Hello, I am doing a degree distribution.

This is the degree distribution without scaled.

The code for the above plot is this:

```julia
histogram(degree, bins=50)
title!("Degree distribution")

```

Because I want to check whether it is power law distribution, so I scaled the x- and y- axe. The code is this:

```julia
histogram(log10.(degree), bins=50, yscale=:log10)
title!("Degree distribution (log-log scale)")

```

And I got the log-log scale plot:

The problem is that it seems the second plot shows a power law distribution. But I do not understand:  
1, after the y axe log10 scaled, the range of the original is 0:60000, after log10 scaled, it should be 0:4.78, why the range of the y in the second plot is 1:10000?

Thank you.

The command `log10.(degree)` changes the numerical values of the x-axis, while the plot scale command `yscale=:log10` doesn’t change anything numerically, it just changes the scale. Note that the y-axis is displayed in log scale and `10^4.78 ~ 60000` (_the exponent varies linearly along the new log-scaled axis_)
