Select the row:
选择行：
row = df.iloc[0]
Plot the row (a pandas.Series):
绘制行 (a pandas.Series)：
row.plot(kind='bar')
For example,
例如，
import pandas as pd
import matplotlib.pyplot as plt
d = {'columns': ['T', 'G', 'C', '-', 'A', 'C', 'T', '-', 'A', 'G', 'T',
'-', 'A', 'G', 'C', '-', 'A', 'T', 'G', 'C'],
'data': [[97, 457, 178, 75, 718, 217, 193, 69, 184, 198,
777, 65, 100, 143, 477, 54, 63, 43, 55, 47]],
'index': [1]}
df = pd.DataFrame(d['data'], columns=d['columns'], index=d['index'])
df.columns.names = ['SAMPLE']
row = df.iloc[0]
row.plot(kind='bar')
plt.show()
yields
产量
