python用plotly绘制折线图为什么跑下来没有图

Question

版本：python3.6、anaconda3(64bit)

问题描述：使用plotly跑下来没有报错，但是也不显示图。即使加上plt.show()，也无济于事，还请大神指点，谢谢。
代码如下：
import plotly.plotly as plt
import plotly.offline as pltoff
from plotly.graph_objs import *

生成折线图

def line_plots(name):
dataset = {'x': [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
'y': [5, 4, 1, 3, 11, 2, 6, 7, 19, 20],
'z': [12, 9, 0, 0, 3, 25, 8, 17, 22, 5]}

data_g = []

tr_x = Scatter(
    x=dataset['x'],
    y=dataset['y'],
    name='y'
)
data_g.append(tr_x)

tr_z = Scatter(
    x=dataset['x'],
    y=dataset['z'],
    name='z'
)
data_g.append(tr_z)

layout = Layout(title="line plots", xaxis={'title': 'x'}, yaxis={'title': 'value'})
fig = Figure(data=data_g, layout=layout)
pltoff.plot(fig, filename=name)
plt.show()

Answer 1

因为你只是写了函数，没有运行你的函数啊，删掉plt.show()这句错误语法，在最后一行加入line_plots('test')就可以了

import plotly.plotly as plt
import plotly.offline as pltoff
from plotly.graph_objs import *

def line_plots(name):
    dataset = {'x': [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
    'y': [5, 4, 1, 3, 11, 2, 6, 7, 19, 20],
    'z': [12, 9, 0, 0, 3, 25, 8, 17, 22, 5]}

    data_g = []

    tr_x = Scatter(
        x=dataset['x'],
        y=dataset['y'],
        name='y'
    )
    data_g.append(tr_x)

    tr_z = Scatter(
        x=dataset['x'],
        y=dataset['z'],
        name='z'
    )
    data_g.append(tr_z)

    layout = Layout(title="line plots", xaxis={'title': 'x'}, yaxis={'title': 'value'})
    fig = Figure(data=data_g, layout=layout)
    pltoff.plot(fig, filename=name)

line_plots('test)
