python绘制图标——subplots_adjust

subplots_adjust
​​​​​​​说明、参数
Adjusting the spacing of margins and subplots调整边距和子图的间距

subplots_adjust(self, left=None, bottom=None, right=None, top=None,
                    wspace=None, hspace=None)

Tune the subplot layout.调整子图布局。

The parameter meanings (and suggested defaults) are:参数含义（和建议的默认值）是：

left  = 0.125  # the left side of the subplots of the figure图片中子图的左侧

right = 0.9    # the right side of the subplots of the figure图片中子图的右侧

bottom = 0.1   # the bottom of the subplots of the figure图片中子图的底部

top = 0.9      # the top of the subplots of the figure图片中子图的顶部

wspace = 0.2   # the amount of width reserved for space between subplots,

               # expressed as a fraction of the average axis width

＃为子图之间的空间保留的宽度，平均轴宽的一部分

hspace = 0.2   # the amount of height reserved for space between subplots,

               # expressed as a fraction of the average axis height

＃为子图之间的空间保留的高度，平均轴高度的一部分

加了这个语句，子图会稍变小，因为空间也占用坐标轴的一部分

fig.subplots_adjust(wspace=0.5,hspace=0.5)
