创建带坐标系的图形的最简单的方法是使作pyplot.subplots（），然后就可以用Axes.plot（）方法来在坐标轴上绘制数据。这种情况下，如果整个figure中只有一个axes对象，就还好，但如果想在一个figure中画很多个子图，就会非常混乱，特别是与seaborn库共同使用时，不可避免会遇到一些ax（axes的通常缩写）的写法
subplots_adjust(left=None, bottom=None, right=None, top=None,wspace=None, hspace=None):调整subplot的位置。 suptitle(t, **kwargs):设置图像标题。t为标题字符串。关键字参数就是Text对象的参数: x:在图形坐标系中,标题的横坐标(范围 0～1) y:在图形坐标系中,标题的纵坐标(范围 0～1) horizontalalig...

You can create an arbitrary number of subplots and axes. If you want to place an axes man- ually, i.e., not on a rectangular grid, use the axes() command, which allows you to specify the location as axes([left, bottom, width, height]) where all values are in fractional (0 to ...
与plt.subplot()相比,plt.subplots()与Python 索引从 0 开始的习惯保持一致。 4.10.4 plt.GridSpec:实现更复杂的排列方式 如果想实现不规则的多行多列子图网格,plt.GridSpace() 是最好的工具。plt.GridSpace() 对象本身不能直接创建一个图形,它只是 plt.subplot() 命令可以识别的简易接口。例如,一个带行列...

Understanding plt.subplots() NotationAlright, enough theory. Now, we’re ready to tie everything together and do some plotting. From here on out, we’ll mostly rely on the stateless (object-oriented) approach, which is more customizable and comes in handy as graphs become more complex....
