Bokehfile_html将返回 HTML+JS 代码以提供数据的交互式绘图。HTML 总大小必须小于 20MB。您的数据需要内联到 HTML 中,否则您可能会遇到 CSRF 错误。确保您已安装 python holoviewsbokehhvplot软件包。例子:

import math
import numpy as np
import pandas as pd
import holoviews as hv
from bokeh.embed import components, file_html
from bokeh.resources import CDN

hv.extension('bokeh')

import hvplot

renderer = hv.renderer('bokeh').instance(fig='html', holomap='auto')

# see https://github.com/ioam/holoviews/issues/1819
def displayHoloviews(hv_plot, html_name="plot.html", width=1000, height=600, renderer=renderer):
  plot = renderer.get_plot(hv_plot).state
  setattr(plot, 'plot_width', width)
  setattr(plot, 'plot_height', height)
  displayHTML(file_html(plot, CDN, html_name))

index = pd.date_range('1/1/2000', periods=1000)
df = pd.DataFrame(np.random.randn(1000, 4), index=index, columns=list('ABCD')).cumsum()

displayHoloviews(hvplot.hvPlot(df).line(y=['A','B','C','D']))
