如何在 python 中使用 Plotly Offline 模式绘制条形图?

How to draw bar chart using Plotly Offline mode in python?

我有一些特点和价值观,例如:

food        3.4   
service     4.2  
environment 4.3 

并且我想使用 Plotly 离线模式绘制条形图(不注册和验证)。 到目前为止,我已经有了使用 Plotly 的离线模式绘制散线的代码:

import plotly
print (plotly.__version__) 
from plotly.graph_objs import Scatter, Layout
plotly.offline.plot({
"data": [
    Scatter(x=[1, 2, 3, 4], y=[4, 1, 3, 7])
],
"layout": Layout(
    title="hello world"
)
})

此代码打开一个 HTML 页面并绘制一条散线。如何修改它以绘制条形图?

import plotly
import plotly.graph_objs

plotly.offline.plot({
"data": [
    plotly.graph_objs.Bar(x=['food','service','environment'],y=[3.4,4.2,4.3])
]
})

要在离线模式下绘制它,请使用:

# Import package 
import plotly 
# Use init_notebook_mode() to view the plots in jupyter notebook
plotly.offline.init_notebook_mode()
from plotly.graph_objs import Scatter,Layout,Bar

trace1 = Bar(x=['food','service','environment'],y=[3.4,4.2,4.3])

# Create chart 
plotly.offline.iplot({
                         "data": [
                                  trace1
                                  ], 
                        "layout": Layout(title="<b>Sample_Title</b>",xaxis= dict(
                                                        title= '<b>X axis label</b>',
                                                        zeroline= False,
                                                        gridcolor='rgb(183,183,183)',
                                                        showline=True
                                                    ),
                                                    yaxis=dict(
                                                        title= '<b>Y axis Label</b>',
                                                        gridcolor='rgb(183,183,183)',
                                                        zeroline=False,
                                                        showline=True
                                                    ),font=dict(family='Courier New, monospace', size=12, color='rgb(0,0,0)'))
                                  })

绘制堆叠图或分组图参考教程: https://github.com/SayaliSonawane/Plotly_Offline_Python/tree/master/Bar%20Chart

有了最近的情节版本(我在 4.1.0),它比以往任何时候都容易。

import plotly.graph_objects as go
animals=['giraffes', 'orangutans', 'monkeys']

fig = go.Figure([go.Bar(x=animals, y=[20, 14, 23])])
fig.show()

如果您想在 Jupyterlab 和网络浏览器之间切换,您可以在开始时分别使用 import plotly.io as piopio.renderers.default = 'jupyterlabpio.renderers.default = 'browser' 进行设置.

import plotly.graph_objects as go
import plotly.io as pio

pio.renderers.default = 'browser'

animals=['giraffes', 'orangutans', 'monkeys']
fig = go.Figure([go.Bar(x=animals, y=[20, 14, 23])])
fig.show()
