Plot 3D-Plots mit Plotly

Question

Ich benutze Flask Framework und Javascript & HTML für Front-End. Ich möchte 3D-Plots in meinem HTML (offline, dh ich möchte nicht auf plotly Website angezeigt werden). Wenn ich den folgenden Code benutze, verliere ich meine dritte Achse, dh das Diagramm, das ich in HTML anzeigen kann, ist nicht mehr 3D, sondern ein 2D. Kann mir bitte jemand sagen wie ich 3D Graphen bekomme.

Ich habe durch documnetation von plotly gegangen, aber Lösung

couldnot

Client-Seite

<script type="text/javascript"> 
    var graphs = {{graphJSON | safe}}; 

     Plotly.plot("section", // the ID of the div, created above 
        graphs.data, 
        graphs.layout || {}); 

</script>

Dies ist, was ich tue, um Python plotly Grafik in eine HTML-Datei zu konvertieren. Zuerst bauen Sie Ihre Figuren dicts statt der Plotly Grafikobjekte Bibliothek:

import numpy as np 
x, y, z = np.random.multivariate_normal(np.array([0,0,0]), np.eye(3), 200).transpose() 
trace1 = dict(
    type = 'scatter3d', 
    x=x, 
    y=y, 
    z=z, 
    mode='markers', 
    marker=dict(
     size=12, 
     line=dict(
      color='rgba(217, 217, 217, 0.14)', 
      width=0.5 
     ), 
     opacity=0.8 
    ) 
) 
layout = dict(
    margin=dict(
     l=0, 
     r=0, 
     b=0, 
     t=0 
    ) 
) 
fig = dict(data = [trace1], layout = layout) 

Nun, hier ist eine Funktion, die ich das plotly Javascript in eine HTML-Datei zu erhalten, schrieb:

import sys 
import os 
from plotly import session, tools, utils 
import uuid 
import json 

def get_plotlyjs(): 
    path = os.path.join('offline', 'plotly.min.js') 
    plotlyjs = resource_string('plotly', path).decode('utf-8') 
    return plotlyjs 


def js_convert(figure_or_data,outfilename, show_link=False, link_text='Export to plot.ly', 
      validate=True): 

    figure = tools.return_figure_from_figure_or_data(figure_or_data, validate) 

    width = figure.get('layout', {}).get('width', '100%') 
    height = figure.get('layout', {}).get('height', 525) 
    try: 
     float(width) 
    except (ValueError, TypeError): 
     pass 
    else: 
     width = str(width) + 'px' 

    try: 
     float(width) 
    except (ValueError, TypeError): 
     pass 
    else: 
     width = str(width) + 'px' 

    plotdivid = uuid.uuid4() 
    jdata = json.dumps(figure.get('data', []), cls=utils.PlotlyJSONEncoder) 
    jlayout = json.dumps(figure.get('layout', {}), cls=utils.PlotlyJSONEncoder) 

    config = {} 
    config['showLink'] = show_link 
    config['linkText'] = link_text 
    config["displaylogo"]=False 
    config["modeBarButtonsToRemove"]= ['sendDataToCloud'] 
    jconfig = json.dumps(config) 

    plotly_platform_url = session.get_session_config().get('plotly_domain', 
                  'https://plot.ly') 
    if (plotly_platform_url != 'https://plot.ly' and 
      link_text == 'Export to plot.ly'): 

     link_domain = plotly_platform_url\ 
      .replace('https://', '')\ 
      .replace('http://', '') 
     link_text = link_text.replace('plot.ly', link_domain) 


    script = '\n'.join([ 
     'Plotly.plot("{id}", {data}, {layout}, {config}).then(function() {{', 
     ' $(".{id}.loading").remove();', 
     '}})' 
    ]).format(id=plotdivid, 
       data=jdata, 
       layout=jlayout, 
       config=jconfig) 

    html="""<div class="{id} loading" style="color: rgb(50,50,50);"> 
       Drawing...</div> 
       <div id="{id}" style="height: {height}; width: {width};" 
       class="plotly-graph-div"> 
       </div> 
       <script type="text/javascript"> 
       {script} 
       </script> 
       """.format(id=plotdivid, script=script, 
          height=height, width=width) 

    #html = html.replace('\n', '') 
    with open(outfilename, 'wb') as out: 
     out.write(r'<script src="https://cdn.plot.ly/plotly-latest.min.js"></script>') 
     for line in html.split('\n'): 
      out.write(line) 

     out.close() 
    print ('JS Conversion Complete') 

Rufen Sie die Funktion als solche:

js_convert(fig, 'test.html') 

Ausbeuten:

<script src="https://cdn.plot.ly/plotly-latest.min.js"></script><div class="e64ff355-dc9b-4590-b73f-7205bab419e4 loading" style="color: rgb(50,50,50);"> \t \t \t \t Drawing...</div> \t \t \t \t <div
