Problem Description

I'm trying to use spyder with the plotly plotting library, but I cannot figure out how to make the plots render in the plots pane, or inline in the command window.

What steps reproduce the problem?

1. Create a plot using plotly
2. Use fig.show()

import plotly.graph_objects as go
go.Figure(go.Scatter(x=[1,2], y=[1,2])).show()

What is the expected output? What do you see instead?

I would expect a plot to appear somewhere.

If you want plotly figures for their interactivity I think you need to use the browser renderer. Either with overriding default renderer:

import plotly.graph_objects as go
go.Figure(go.Scatter(x=[1,2], y=[1,2])).show(renderer='browser')

or set the default:

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

See: https://plotly.com/python/renderers/#setting-the-default-renderer

In the case of static images, I thought it was supposed to work with QtConsole/IPython/Spyder (https://plotly.com/python/renderers/#static-image-renderers). Note that this requires kaleido. For example:

import plotly.graph_objects as go
go.Figure(go.Scatter(x=[1,2], y=[1,2])).show(renderer='png')

But the console freezes for me trying to do that...

Edit: I was running spyder-kernels 2.5.0 in that env, but updating to 2.5.1 (also updated ipykernel to 6.29.3) and it works with renderer='png' and renderer='svg' - static plot shows in the plots pane.
