Is there a way to add additional degrees in windrose(default degrees marked as every 45° )? what I want to do is, mark degrees at every 22.5° instead of every 45°(0°,22.5°,45°,67.5° and so on).
I read the plotly windrose documentation, but couldn’t able to find a suitable way to fix this.
code:
fig = px.bar_polar(df, r="Frequency", theta="wind_dir_Range", color="Wind_Speed", color_discrete_map={"0-10 km/h": "purple", "10-20 km/h": "cyan","20-30 km/h":"limegreen","30-40 km/h": "red"} ) fig.show()

Answer
- have used alternate source of data… doesn’t generate a good chart
- however it does show that you can adjust tick size using dtick
import plotly.express as px df = px.data.wind() df = df.assign(Direction=np.random.uniform(0,360,len(df))) fig = px.bar_polar(df, r="frequency", theta="Direction", color="strength", template="plotly_dark", color_discrete_sequence= px.colors.sequential.Plasma_r) fig.update_layout(polar={"angularaxis":{"dtick":45/2}})
