color discrete sequence in a plotly graph objects

Question

how can i plot a pie chart with color sequence while using plotly.graph_objects instead of plotly.express. In plotly.express is it very easy to do with the property "color_discrete_sequence". Is there something similar? Thank you

You could use the color attribute of the marker if I understand your problem correctly. Just get the color Sequence you want.

import plotly.graph_objects as go 
import plotly.express as px 

colors = px.colors.sequential.RdBu 

fig = go.Figure(data=[go.Pie(labels=['Oxygen','Hydrogen','Carbon_Dioxide','Nitrogen'],
                             values=[4500,2500,1053,500])])
fig.update_traces(hoverinfo = 'label+percent', textinfo='value', textfont_size=20,
                  marker=dict(color=colors, line=dict(color = '#000000',  width=2)))
fig.show()
