Plotly python: completely free?

Question

I am a little puzzled by the "free" state of the Python library, Plotly.

It says on its website that it is free and open source, but at the same time it says that you need a Plotly account if you want to publish graphics on the Internet.

I want to create a web application using Python and JavaScript story libraries - can I do this without a story account?

Answer 1

Short: Yes python library is free .

Answer with sources:

I also started using the plot, and I completely agree with you that at first it is not clear whether the plugin is free or not. Here are the facts I found about the plot:

• The python library is free and published in the MIT-License section. Source
• JS-lib has been published under the MIT license since 2015 ( Source ). Thus, it is also free since 2015. There is also a link to the open source plly.js website announcement from 2015. Source

The open source announcement also has information about other plotly libraries:

The R, Python, and MATLAB clients for Plotly were always open source, and the main graphics layer, plotly.js, was closed. Now the whole stack is open source. Source

The accounts you can create on your website are intended only for posting charts on the Internet. As with a free account, you can post one private schedule, with a professional account you can post unlimited private / public schedules. Link

This is a fairly common business model that makes the code open source and makes money with the provision of support / or on the example of graphical hosting schedules for you if you do not want to place them yourself.

Answer 2

Yes, it is completely free. You can also use the professional features provided in the online version for free, and you do not need an online account to do this. All graphs created using this can be stored privately (this has nothing to do with the online account until you link them together).

I also created sample tutorials on creating interactive graphs using a stand-alone library in Python. You can access it at: https://github.com/SayaliSonawane/Plotly_Offline_Python

Answer 3

You can use the plot offline, as well as download the Dash library. To use the plotly method offline, you can use the following code

## plotly libraries from plotly import __version__ from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot import plotly.graph_objs as go init_notebook_mode(connected=True) 

Answer 4

Yes, the story library is a free library. You can use it in several ways:

 from plotly.offline import init_notebook_mode init_notebook_mode(connected=True) 

or for publishing on the Internet why not use Dash :

 import dash
