I'm trying to use plotly inside of vscode without a jupyter notebook.

When i use

import plotly.express as px

fig=px.line(x=[1,2,3,4],y=[1,4,9,16])
fig.show(renderer='vscode')

i only see some output in the terminal:

When i omit the renderer argument, like

import plotly.express as px

fig=px.line(x=[1,2,3,4],y=[1,4,9,16])
fig.show()

the plot opens in my default browser, which is not what i want.

Is it either possible to show the figure directly in vscode or can it be opened in a browser tab inside of vscode so i don't have to switch windows?

If you want to use the built-in notebook of VS Code, another setting may be necessary to view maps:

import plotly.io as pio
pio.renderers

gives this:

Renderers configuration

Default renderer: 'vscode'
Available renderers:
    ['plotly_mimetype', 'jupyterlab', 'nteract', 'vscode',
     'notebook', 'notebook_connected', 'kaggle', 'azure', 'colab',
     'cocalc', 'databricks', 'json', 'png', 'jpeg', 'jpg', 'svg',
     'pdf', 'browser', 'firefox', 'chrome', 'chromium', 'iframe',
     'iframe_connected', 'sphinx_gallery', 'sphinx_gallery_png']

I needed to set:

pio.renderers.default = "notebook_connected"

to be able to render background maps (e.g. with px.scatter_geo() ).

All the other (non-map) visualizations worked even without this setting, though.

  1. For plotting using "plotly".

    "Plotly" is based on a web application that analyzes a python plotting library. Its drawing effect is displayed on the html page by default, so it is viewed in the browser by default.

    In addition to "Jupyter notebook" can be used to display the drawing in VSCode, we can also view the drawing in the "Interactive Window" window:

    [Right-click on the code and select "Run Current File in Interactive Window".]

    enter image description here

  2. Use "matplotlib" to plot.

    "Matplotlib" is a python plotting library. When we use it to plot, the results will be displayed in the python plot window:

    enter image description here

  3. For the built-in browser of VSCode, we usually use it to open the file in the browser through the html file, and the html can be directly rendered and displayed in the browser.

One option is to set the default renderer, this works in the cell style mode for Python in VSCode:

import plotly.io as pio
pio.renderers.default = "vscode"

With the current VS code (2022 Feb) and having your python code run at the interactive window the following render seems to work smoother.

pio.renderers.default = "notebook"

Just my two cents to this topic. This minimal working example runs fine in VS code (2022 May)

import plotly.io as pio
import plotly.express as px

pio.renderers.default = "notebook"
fig = px.bar(x=["a", "b", "c"], y=[1, 3, 2])
fig.show()

example plotly bar plot

Ran into the same issue with bokeh. Apparently, jupyter makes this difficult. Panel helped me:

import panel as pn

pn.extension()
