Hi there,

Do you know if there is a plotly graph as this one, or one that I could adapt to get smtg similar?

I actually wanted something like the wind rose but with the centre empty, as this one.
Thanks for your help!!

Hi Cecilia,

So From what I can see, it doesn’t look like having a hole is native to the Plotly scatter_polar chart, like pie charts, for example, have the hole attribute. You could do something like adding a circle in the middle of the chart with some text: Adding a circle to a Plotly chart. It might hide some text, so unless you have a clearly stated range for the r values, it might not be ideal.

Thanks @louisrivers, I’ll play with that and see if I can get the graphs as I want. :upside_down_face:

Here is the solution for a Scatterpolar plot:

layout = go.Layout(
                 polar= dict( hole = 0.75)

The 0,75 is that 75% of the axe will be a hole:
