Python 如何在没有jupyter的情况下将此交互式绘图导出到浏览器中查看?,python,plotly,jupyter,ipywidgets,Python,Plotly,Jupyter,Ipywidgets,我有一个python交互式绘图: import ipywidgets as widgets import plotly.graph_objects as go from numpy import linspace def leaf_plot(sense, spec): fig = go.Figure() x = linspace(0,1,101) x[0] += 1e-16 x[-1] -= 1e-16 positive = sense*x/(

我有一个python交互式绘图:

import ipywidgets as widgets
import plotly.graph_objects as go 
from numpy import linspace


def leaf_plot(sense, spec):
    fig = go.Figure()

    x = linspace(0,1,101)
    x[0] += 1e-16
    x[-1] -= 1e-16

    positive =  sense*x/(sense*x + (1-spec)*(1-x)) 
                                                    #probability a person is infected, given a positive test result, 
                                                    #P(p|pr) = P(pr|p)*P(p)/P(pr)
                                                    #        = P(pr|p)*P(p)/(P(pr|p)*P(p) + P(pr|n)*P(n))
                                                    #        =   sense*P(p)/(  sense*P(p) +(1-spec)*P(n))
    negative =  1-spec*(1-x)/((1-sense)*x + spec*(1-x))

    fig.add_trace(
        go.Scatter(x=x, y  = positive, name="Positive",marker=dict( color='red'))
    )

    fig.add_trace(
        go.Scatter(x=x, y  = negative, 
                   name="Negative", 
                   mode = 'lines+markers',
                   marker=dict( color='green'))
    )
 
    fig.update_xaxes(title_text = "Base Rate")
    fig.update_yaxes(title_text = "Post-test Probability")
    fig.show()

sense_ = widgets.FloatSlider(
    value=0.5,
    min=0,

display(ui, out)
如何将其导出,以便在浏览器中将其视为独立的网页(如HTML),同时保留互动性(如中)

使用plotly的fig.write_html()选项,我得到了一个独立的网页,但这样我就失去了滑块

经过一些修改,plotly最多允许使用一个滑块(plotly地物对象中不包括IPyWidget)

此外,在plotly中,所述滑块基本上控制预先计算的轨迹的可见性(参见示例),这限制了交互(有时参数空间很大)

最好的方式是什么


(我不必坚持使用plotly/ipywidgets)

使用plotly,在创建图形后,保存它:

fig.write_html("path/to/file.html")
也可以在函数中尝试此参数:

动画选项:dict或None(默认无) 要传递给函数的自定义动画参数的dict Plotly.js中的Plotly.animate。看见 获取可用选项。如果图形不包含,则无效 帧,或自动播放为假


否则,请查看此处以获得一些建议:

您需要对事情进行一些修改,但您可以通过和实现您想要的

首先,需要修改leaf_plot()以返回地物对象

from numpy import linspace


def leaf_plot(sense, spec):
    fig = go.Figure()

    x = linspace(0,1,101)
    x[0] += 1e-16
    x[-1] -= 1e-16

    positive = sense*x/(sense*x + (1-spec)*(1-x)) 
    negative = 1-spec*(1-x)/((1-sense)*x + spec*(1-x))

    fig.add_trace(
        go.Scatter(x=x, y  = positive, name="Positive",marker=dict( color='red'))
    )

    fig.add_trace(
        go.Scatter(x=x, y  = negative, 
                   name="Negative", 
                   mode = 'lines+markers',
                   marker=dict( color='green'))
    )
    
    fig.update_layout(
    xaxis_title="Base rate",
    yaxis_title="After-test probability",
    )

    return fig
然后编写dash应用程序:

from jupyter_dash import JupyterDash
import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output


# Build App
app = JupyterDash(__name__)
app.layout = html.Div([
    html.H1("Interpreting Test Results"),
    dcc.Graph(id='graph'),
    html.Label([
        "sensitivity",
        dcc.Slider(
            id='sensitivity-slider',
            min=0,
            max=1,
            step=0.01,
            value=0.5,
            marks = {i: '{:5.2f}'.format(i) for i in linspace(1e-16,1-1e-16,11)}
        ),
    ]),
    html.Label([
        "specificity",
        dcc.Slider(
            id='specificity-slider',
            min=0,
            max=1,
            step=0.01,
            value=0.5,
            marks = {i: '{:5.2f}'.format(i) for i in linspace(1e-16,1-1e-16,11)}
        ),
    ]),
])

# Define callback to update graph
@app.callback(
    Output('graph', 'figure'),
    Input("sensitivity-slider", "value"),
    Input("specificity-slider", "value")
)
def update_figure(sense, spec):
    return leaf_plot(sense, spec)

# Run app and display result inline in the notebook
app.run_server()
如果您在jupyter笔记本中执行此操作,您将只能在本地访问您的应用程序


如果您想发布,可以尝试

是!您需要使用OP中指出的绘图指定保存函数中的类型,这会失去很多交互性。所有的滑块和其他iPyWidget都不见了。它们不是plotly figure对象的一部分。您知道这里使用的是什么后端吗:?
