这篇我们用matplotlib从构造最简单的bar一步一步向复杂的bar前行。什么是最简单的bar,看如下语句你就知道她有多么简单了: importmatplotlib.pyplot as plt plt.bar(left=0,height=1) plt.show() 执行效果: 是的,三句话就可以了,是我见过最简单的绘图语句。首先我们import了matplotlib.pyplot ,然后直接调用其bar...
plt.bar(left = ( 0, 1),height = ( 1, 0. 5),width = 0. 35) plt.show() 此时又来需求了,我需要标明x,y轴的说明。比如x轴是性别,y轴是人数。实现也很简单,看代码: importmatplotlib.pyplot as plt plt.xlabel(u ‘性别’) plt.ylabel(u ‘人数’) plt.bar(left = ( 0, 1),height =...

Firstly, we have to know the syntax to create a horizontal bar chart: matplotlib.pyplot.barh(y, width, height=0.8, left=none, align='center', **kwargs) The parameters used are described below: y:specify coordinates of the y bars. ...
