when you see how to use - what are you trying to do?
The simplest thing you can do is say download(self.plot.to_image())
Here’s some extra hints about hot to use it from the anvil api docs
https://anvil.works/docs/api/anvil#Plot_attributes
And the possible options from the plotly docs
https://plotly.com/python-api-reference/generated/plotly.graph_objects.Figure.html?highlight=to_image#plotly.graph_objects.Figure.to_image
looking at your other question you can add the options ...to_image({'format':'svg'}
)` (it looks like pdf doesn’t work as a format)
But then if you need a pdf you could use anvil’s pdf rednerer to do that…
I’m not sure exactly what you mean by HTMLtemplate
option.
