我尝试了以下方法:
using Plots.jl; gr()
histogram(randn(1000),yaxis=(:log10))
它产生以下错误
Error showing value of type Plots.Plot{Plots.GRBackend}:

如何使用 Plots.jl 生成对数 y 轴的直方图？我在 MacOS 10.11.6 上使用 Julia 版本 0.5.0-rc3+0，Plots.jl 版本 0.9.1。
最佳答案
问题是您的轴范围为零，即日志空间中的 -Inf。有几种方法可以解决这个问题，最简单的方法可能是在轴上强制下限:
using Plots; gr()
histogram(randn(1000), yaxis = (:log10, (1,Inf)))
