python:绘制直方图(Histogram) 技术标签: python python简介 本文主要总结如何绘制直方图,以及常用的使用场景。 什么是直方图:一个随机变量在各个取值区间有个概率分布,将其绘制出来:x轴为等间隔的取值区间(bins),y轴为该区间的频数(可归一化),即直方图。 接口 Signature: plt.hist( x, bins=None, range=None, ...
Host, run, and code Python in the cloud! Matplotlibcan be used to create histograms. A histogram shows the frequency on the vertical axis and the horizontal axis is another dimension. Usually it has bins, where every bin has a minimum and maximum value. Each bin also has a frequency betwe...
