使用绘图离线将图形生成为图像

问题描述

$ p
$ b

  plotly.offline.plot（{ data：data，layout：layout}）
  

效果很好。该图形正确生成并且html文件被保存到我的当前目录。

我想要的是，使用图标离线，是保存图像（.png，.jpg等）文件。我在正确的轨道上吗？我需要从这里做什么？

解决方案

试试这个

  import plotly.offline 
 import plotly.graph_objs as go 
 
 plotly.offline.plot（{data：[go.Scatter（x = [1,2,3,4]，y = [4,3,2,1]）]，
layout：go.Layout（title =hello world）}，
 image ='jpeg'，image_filename ='test'）
  

并在Chrome中打开

I am working with plotly offline and am able to generate an html file using

plotly.offline.plot({"data": data, "layout": layout})

It works great. The graph is generated correctly and the html file gets saved to my current directory.

What I want, though is, using plotly offline, is to have an image (.png, .jpg, etc.) file saved instead. Am I on the right track? What do I need to do from here?

解决方案

Try this

import plotly.offline
import plotly.graph_objs as go

plotly.offline.plot({"data": [go.Scatter(x=[1, 2, 3, 4], y=[4, 3, 2, 1])],
                     "layout": go.Layout(title="hello world")},
                     image='jpeg', image_filename='test')

and open it in Chrome
