If you’re using plotly.express you can use the line_close=True parameter, otherwise you’ll have to manually duplicate the first point at the end of your series.

For a “popup” you will have to use annotations and shapes: https://plotly.com/python/text-and-annotations/ and https://plotly.com/python/shapes/

Hello,

So if we use go.Scatterpolar with plotly.graphs_objects we can’t close the last point with the first ?
I’m using this instead of plotly.express because I want create a radar charte with 2 parameters.
It’s possible to do that also with plotly.express ?

Thanks
Simon

Yes, you can use Plotly Express to make radar charts with multiple traces, by setting the color argument.

You can also close lines with go.Scatterpolar by repeating the first point in your trace at the end.

Hey Nicolas,
I know this thread seems to be a little bit outdated, but I could not close my lines either with go.Scatterpolar. Could you describe what exactly you mean by “repeating the first point in your trace”?
My values come from a dataframe, and if I were to repeat values, wouldn’t that create a new attribute/column?

Best Regards
