如何在Python直方图中包含对数垃圾箱 [英] How to have logarithmic bins in a Python histogram

问题描述

据我所知，直方图函数中的Log = True选项仅指y轴.

As far as I know the option Log=True in the histogram function only refers to the y-axis.

P.hist(d,bins=50,log=True,alpha=0.5,color='b',histtype='step')

我需要将垃圾箱在log10中等距放置.有什么可以做到的吗?

I need the bins to be equally spaced in log10. Is there something that can do this?

推荐答案

使用logspace()创建几何序列，并将其传递给bins参数.并将xaxis的比例设置为对数比例.

use logspace() to create a geometric sequence, and pass it to bins parameter. And set the scale of xaxis to log scale.

import pylab as pl
import numpy as np

data = np.random.normal(size=10000)
pl.hist(data, bins=np.logspace(np.log10(0.1),np.log10(1.0), 50))
pl.gca().set_xscale("log")
pl.show()
