首先,我们需要假设你正在使用Python的数据分析库Pandas来处理这个数据集,并且已经将数据加载到DataFrame `courses` 中。如果你想要绘制的是名为"Reading frequency (non-fiction books/journals)"的数据列的直方图,你可以按照以下步骤操作:
```python
import pandas as pd
import matplotlib.pyplot as plt
# 假设"data_column_name"是你提到的具体列名
data_column_name = 'Reading frequency (non-fiction books/journals)'
# 检查数据列是否存在
if data_column_name in courses.columns:
# 绘制直方图
histogram = courses[data_column_name].hist(bins=range(0, max(courses[data_column_name])+1),
title='Histogram of Reading Frequency',
xlabel=data_column_name,
ylabel='Frequency')
# 显示图表
plt.show()
else:
print(f"'{data_column_name}' not found in the dataset.")
