Question

我正在学习有关将 Bokeh 连接到网络应用程序的教程，但我无法显示图表，只有一些显示 Bokeh 教程的文字。我发现很难找到一个可靠的散景教程（如果有人对库显示可以随用户输入更改的图形有任何其他建议，我很乐意查看它们）所以我不是非常确定如何解决此问题。

Python 代码

from flask import Flask, render_template
from bokeh.plotting import figure
from bokeh.embed import components
from bokeh.resources import CDN

app = Flask(__name__)

@app.route('/')
def index():
    return 'Hello World!'

@app.route('/dashboard/')
def show_dashboard():
    plots = []
    plots.append(make_plot())

    return render_template('dashboard.html', plots=plots)

def make_plot():
    plot = figure(plot_height=300, sizing_mode='scale_width')

    x = [0,1,2,3,4,5,6,7,8,9]
    y = [2**v for v in x]

    plot.line(x, y, line_width=4)

    script, div = components(plot)
    return script, div

if __name__ == '__main__':
    app.run(debug=True)
