Question

我正在尝试使用字典绘制多个y轴图，并得到此错误TypeError：'NoneType'对象不可调用。我尝试了多次尝试，但无法绘制图形。我正在使用2.7.0版

这是我完整的脚本

import plotly.graph_objs as go


params_list = {



"spd": {
"plot-graph": [
  {
    "x-axis": [1,6,12],
    "y-axis": [.5,3,6],
    "y-axis-title": "y 0",
    "layout" : {
    "title" : "sample 1",
    "titlefont": "",
    "tickfont": "",
    "side": "",
    "overlaying": ""}
  },
  {
    "x-axis": [3,9,14],
    "y-axis": [4,2,9],
    "y-axis-title": "sample 2",
    "layout" : {
    "title": "y 2",
    "titlefont": "rgb(120, 113, 159)",
    "tickfont": "rgb(130, 103, 189)",
    "side": "right",
    "overlaying": "y"}
  },
  {
    "x-axis": [12, 10, 5],
    "y-axis": [8, 4, 11],
    "y-axis-title": "sample 3",
    "layout" : {
    "title": "y3",
    "titlefont": "rgb(112, 103, 189)",
    "tickfont": "rgb(110, 103, 189)",
    "side": "right",
    "overlaying": "y"}
}
]
}
}

plot_graph = []


listTrace = []

cnt = 0;

#graph with multiple y axes            

layout_kwargs = {'title' : "My TEST Graph"}            

graph_list = params_list['spd']['plot-graph']

graph_list = [{ k: v for k, v in d.items() if v } for d in graph_list]

cnt = 0       

for params in graph_list:
   trace = go.Scatter(x=params['x-axis'],y = params["y-axis"], name =          params["y-axis-title"], yaxis='y' + str(cnt + 1) * (cnt > 0))


   y_axis_name = 'yaxis' + str(cnt + 1) * (cnt > 0)
   layout = {k: v for k, v in params['layout'].items() if v }
   if layout.has_key('titlefont'):
       layout['titlefont'] = dict(color = layout['titlefont'])

   if layout.has_key("tickfont"):
       layout["tickfont"] = dict(color = layout['tickfont'])
   layout_kwargs[y_axis_name] = layout
       listTrace.append(trace)                
   cnt = cnt + 1

fig = go.Figure(data=listTrace, layout=go.Layout(**layout_kwargs))
fig.show()

以前的错误是在go.Figure方法中，但现在在fig.show（）中。

Answer 1

fig.show()是在Plotly版本4中引入的，但如上所述，您在版本2中。

密谋Fig.show（）给出TypeError：'NoneType'对象不可调用
