matplotlib.pyplot.xlim() 官方文档

matplotlib.pyplot.xlim(*args, **kwargs)

获取或者是设定x座标轴的范围，当前axes上的座标轴。

有两种参数输入方式

```
plt.xlim(num1, num2)
```

在这里插入图片描述

```
plt.xlim(xmin=num1,xmax=num2)
```

在这里插入图片描述

matplotlib.pyplot.ylim 官方文档

内容与x一样

matplotlib.pyplot.axis 官方文档

matplotlib.pyplot.axis(*v, **kwargs)

参数详解：

xmin, xmax, ymin, ymax : float, optional

option : str

Value	Description
‘on’	Turn on axis lines and labels.
‘off’	Turn off axis lines and labels.
‘equal’	Set equal scaling (i.e., make circles circular) by changing axis limits.
‘scaled’	Set equal scaling (i.e., make circles circular) by changing dimensions of the plot box.
‘tight’	Set limits just large enough to show all data.
‘auto’	Automatic scaling (fill plot box with data).
‘normal’	Same as ‘auto’; deprecated.
‘image’	‘scaled’ with axis limits equal to data limits.
‘square’	Square plot; similar to ‘scaled’, but initially forcing `xmax-xmin = ymax-ymin`.
