今天我们要做的图如下格式：

平时时间太少，不说废话，直接给大家发布Python代码了：

import numpy as np

import matplotlib.pyplot as plt

up_num = (-210, -300, -450, -175, -287)

down_num = (295, 320, 450, 106, 65)

fig, ax = plt.subplots()

ind = np.arange(len(up_num)) # the x locations for the groups

width = 0.35 # the width of the bars

rects1 = ax.bar(ind, up_num, width, color='green', label='up_num')

rects2 = ax.bar(ind, down_num, width, color='red', label='down_num')

# Add some text for labels, title and custom x-axis tick labels, etc.

ax.set_ylabel('Gene number')

ax.set_title('The DEGs')

ax.set_xticks(ind)

ax.set_xticklabels(('Treatmen_1', 'Treatmen_2', 'Treatmen_3', 'Treatmen_4', 'Treatmen_5'))

ax.legend(loc = 'best')

ax.spines['right'].set_color('none')

ax.spines['top'].set_color('none')

ax.set_ylim(-600,600)

#ax.spines['bottom'].set_position(('data', 0))

#ax.spines['left'].set_position(('data', 0))

plt.show()

plt.savefig('C:/Users/Administrator/Desktop/result.pdf')
