并列条形图python

要绘制并列条形图，可以使用Python中的Matplotlib库。下面是一个示例代码来绘制并列条形图：

import matplotlib.pyplot as plt
import numpy as np

waters = ('高新', '历城', '市中', '历下', '槐荫')
high = [8, 5, 3, 2, 4]
low = [40, 25, 25, 25, 7]
bar_width = 0.3

index_male = np.arange(len(waters))
index_female = index_male + bar_width

plt.bar(index_male, height=high, width=bar_width, color='mediumaquamarine', label='最高')
plt.bar(index_female, height=low, width=bar_width, color='salmon', label='最低')

plt.legend()
plt.xticks(index_male + bar_width/2, waters)
plt.ylabel('薪资单位：K')
plt.title('各个区最高薪资和最低薪资统计表')

plt.show()

这段代码使用了Matplotlib库来绘制并列条形图。首先定义了需要显示的数据和标签，然后使用`plt.bar`函数分别绘制最高薪资和最低薪资的条形图。设置`bar_width`参数用于调整条形的宽度，`index_male`和`index_female`分别是最高薪资和最低薪资的横坐标位置。最后使用`plt.legend`添加图例，`plt.xticks`设置横坐标刻度，`plt.ylabel`设置纵坐标标题，`plt.title`设置图形标题，最后使用`plt.show`显示图形。

这样就可以绘制出一个并列条形图，其中比较了各个区最高薪资和最低薪资的数据。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
