我们可以通过直接指定bar方法里面的align=”center”就可以让文字居中了。 importmatplotlib.pyplot as plt plt.xlabel(u ‘性别’) plt.ylabel(u ‘人数’) plt.xticks(( 0, 1),(u ‘男’,u ‘女’)) plt.bar(left = ( 0, 1),height = ( 1, 0. 5),width = 0. 35,align = “center”) pl...

# lets create a simple bar chart# x-axis is shows the subject and y -axis shows the markers in each subject例子:subject =marks =plt.bar(subject,marks)plt.show() 请输入图片描述 #let’s do some customizations#width – shows the bar width and default value is 0.8#color – shows the ba...
plt.bar(left=(0,1),height=(1,0.5),width=0.35) plt.show() 注意这里的中文一定要用u(3.0以上好像不用,我用的2.7),因为matplotlib只支持unicode。接下来,让我们在x轴上的每个bar进行说明。比如第一个是“男”,第二个是“女”。 importmatplotlib.pyplot as plt ...

To create a bar chart with pyplot, we use theplt.bar()function. Inside of the plt.bar function are several parameters. In the picture above, I’ve shown four:x,height,width, andcolor. The plt.bar function has more parameters than these four, but these four are the most important for...
