在bokeh图中选择和更新pandas数据框列

import pandas as pd
from bokeh.plotting import figure, show
from bokeh.io import output_notebook

data = {'x': [1, 2, 3, 4, 5],
        'y': [6, 7, 8, 9, 10]}
df = pd.DataFrame(data)

output_notebook()

p = figure(title='Bokeh图', x_axis_label='X轴', y_axis_label='Y轴')

# 选择数据框的某一列
x = df['x']

# 更新数据框的某一列
df['y'] = df['y'] * 2

# 添加选择的列
p.line(x, df['y'], legend_label='Y列')

# 添加更新后的列
p.line(x, df['y'], legend_label='更新后的Y列', line_color='red')

show(p)
