更改 100% 堆积条形图中的颜色绘图 python

2024-06-02 • 问答

我正在尝试在 plotly 中更改堆叠的 100% 条形图的颜色。

我有以下数据框和代码：

import pandas as pd
import plotly
import plotly.express as px
from plotly.offline import plot

df = pd.DataFrame([["A","Jan","20%"],["A","Fev","10%"],"Mar","15%"],"Apr",["B",["C","25%"],"30%"],["D","40%"],"50%"],"45%"],"50%"]],columns=["type","month","percentage"])

colors = plotly.colors.qualitative.Prism

fig=px.bar(df,x='month',y='percentage',color=df['type'],barmode ='stack',text = df['percentage'])


fig.update_traces(textfont_size=12,marker_color = colors)

fig.update_layout(title = {'text': "Title",'x':0.5,'xanchor': 'center'},title_font_size=30,legend=dict(yanchor="bottom",y=0.0,xanchor="right",x=1.2),legend_font_size=16,xaxis_title = 'Months',yaxis_title ='%',xaxis_tickangle=-45,width = 1000,height = 600)
fig.show()

但我得到以下信息：

更改整个条形的颜色，而不是更改每个条形部分的颜色。

我想要的是把原来的蓝、红、绿、紫改成：

（这就是我在 marker_color = colors 中没有 fig.update_traces 时得到的结果，尝试根据需要更改颜色。）

我该怎么做才能正确？

colors = plotly.colors.qualitative.Prism fig = px.bar(df,x='month',y='percentage',color=df['type'],barmode='stack',text=df['percentage'].astype(str) + '%',# Add Percent Sign color_discrete_sequence=colors) # Don't forget to remove from update_traces fig.update_traces(textfont_size=12)

import pandas as pd import plotly import plotly.express as px df = pd.DataFrame([["A","Jan",20],["A","Fev",10],"Mar",15],"Apr",["B",["C",25],30],["D",40],50],45],50]],columns=["type","month","percentage"])
