Use matplotlib to draw boxplots (boxplot)
Doing machine learning often requires visualizing data. This time I introduce boxplot. Because I often use it in data analysis, I created a small function to make it more convenient for me to use in the future. – boxplot has the following advantages: 1. Display the distribution of data graphically, making it clear at a […]

Foreword: Continue from last time Tips: The following is the text of this article, the following cases are for reference 1. Draw histogram Use hist() to draw a histogram Example: Draw a line histogram with 8 rectangular bar fills, the code is as follows : import numpy as np import matplotlib.pyplot as plt scores = […]
Use matplotlib to draw histograms, pie charts, scatter plots, and error bar plots
Before drawing the charts, let us first have a brief understanding of each chart so that we can understand and better use each chart. Then we will give examples of data to draw the charts so that we can easily understand and accept them. Histogram A histogram, also known as a quality distribution chart, is […]
Use matplotlib to draw histograms, pie charts, scatter plots, and error bar plots
1. Draw histogram 1.1 Draw histogram Use pyplot’s hist() function to quickly draw a histogram. The syntax format of the hist() function is as follows: hist(x,bins=None,range=None,density=None,weights=None, rcumulative=False,bottom=None,histtype=’bar’,align=’mid’, orientation=’vertical’,rwidth=None,log=False,label=None, stacked=False,normed=None,*,data=None,**kwargs) The meanings of the common parameters of this function are as follows. x: Represents the data of the x-axis, which can be a single array or […]
