ax = plt.subplot(111)什么意思

这段代码是在Python中使用matplotlib库绘制图表时常见的用法之一。其中的ax是子图的句柄，plt是matplotlib库，subplot函数是在图形窗口中创建子图的方法。而括号中则是用来表示子图的位置和布局的参数，(111)表示只用一个子图，并且该子图覆盖整个绘图区域。具体来说，该函数返回一个Axes对象，可以通过该对象调用matlplotlib库的各种方法实现对图表的定制化配置。

ax= plt.subplot

在这个代码中，ax = plt.subplot()的作用是创建一个包含单个子图的figure和axes对象。这个子图是一个标准的2D坐标轴对象，可以用来绘制图形和设置图形属性。 [3]<span class="em">1</span><span class="em">2</span><span class="em">3</span>

ax = plt.subplot(111)

This line of code creates a subplot with one row and one column, and sets the current axis to ax. The number 111 is a shorthand for specifying the subplot layout. The first digit represents the number of rows, the second digit represents the number of columns, and the third digit represents the index of the current subplot, counting from left to right and top to bottom. Since there is only one subplot in this case, the shorthand is 111.
