将csv数据加载到bokeh时出现问题

import pandas as pd

# 尝试加载CSV文件
try:
    df = pd.read_csv('path_to_your_file.csv', encoding='utf-8')
except Exception as e:
    print(f"Error loading CSV: {e}")

from bokeh.plotting import figure, show
from bokeh.io import output_notebook

# 假设df是已加载的DataFrame
output_notebook()  # 在Jupyter Notebook中显示图表

p = figure(title="Example Plot", x_axis_label='X', y_axis_label='Y')
p.line(df['x_column'], df['y_column'], legend_label="Line", line_width=2)

show(p)

from bokeh.plotting import figure, curdoc
from bokeh.models import ColumnDataSource

source = ColumnDataSource(df.head(1000))  # 只加载前1000行数据

p = figure(title="Example Plot")
p.line('x_column', 'y_column', source=source)

curdoc().add_root(p)

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

# 加载CSV数据
df = pd.read_csv('your_data.csv')

# 设置输出环境（例如Jupyter Notebook）
output_notebook()

# 创建图表
p = figure(title="CSV Data Visualization", x_axis_label='X Axis', y_axis_label='Y Axis')
p.line(df['x'], df['y'], legend_label="Data Line", line_width=2)

# 显示图表
show(p)
