Question about Treemap and sunburst chart of Plotly Express.The color_discrete_map of parameters is not work

I am a student and I want to use plotly.express to make a dashboard for my homework.I want to unify the colors of the company In every chart.So I use color_discrete_map to set color for each company.but it is not working in Treemap and sunburst chart.

For example:

df = pd.DataFrame({‘company’:[“Java”,“mongoDB”,“Python”,“C++”],
colors = {“Java”:‘orange’,“mongoDB”:“Red”,“Python”:“yellow”,“C++”:“green”}
px.treemap(df,path = [‘company’],values=“popularity”,color = “company”,color_discrete_map = colors).show()
px.bar(df,x = ‘company’,y=“popularity”,color = “company”,color_discrete_map = colors)

In this code The color for each company of treemap does not followed color_discrete_map ,but color of bar chart has followed followed color_discrete_map

This problem has troubled me for several days.

Hope guys can help me. Thank you

Hi @Cmccm123, welcome to the forum! There was indeed a bug which we have fixed in plotly 4.5.1, which we released last week. Could you please try to upgrade to the latest version and see if the problem is solved?

@Emmanuelle I use 4.8.1 and seems the bug is still there. The color_discrete_map that I used, does not work with px.treemap but works with px.bar. I want to unify the colors in both charts, but I am unable to. Please help! Thank you!
