二 matplotlib命令与格式：坐标轴数值格式(日期格式,百分比,科学记数)
https://blog.csdn.net/helunqu2017/article/details/78650782
import matplotlib.pyplot as plt
ax=plt.gca()
fmt='%.0f%%'
yticks = mtick.FormatStrFormatter(fmt)
ax.yaxis.set_major_formatter(yticks)
一 Matplotlib subplots_adjust hspace so titles and xlabels don't overlap
from matplotlib import pyplot as plt
subplots_adjust子图调节
fig = plt.figure()
fig.subplots_adjust(left=1,right=2.5)
fig.canvas.draw()
matplotlib.pyplot.subplots_adjust(*args, **kwargs)subplots_adjust(left=None, bottom=None, right=None, top=None, wspace=None, hspace=None)
left =0.125# 子图(subplot)距画板(figure)左边的距离
right =0.9# 右边
bottom =0.1# 底部
top =0.9# 顶部
wspace =0.2# 子图水平间距
hspace =0.2# 子图垂直间距
