Plotly graph_objects 仅更改部分文本的字体颜色

Question

我正在尝试在 Plotly 中制作条形图，并希望部分标题与条形图具有相同的颜色，但不是所有文本。

这是我迄今为止所尝试过的。打印显示了我希望得到的东西。

import pandas as pd
import plotly.graph_objects as go

def create_barchart(df):
    fig = go.Figure()
    fig.add_trace(go.Bar(
        x=df["value"],
        y=df["col_name"],
        orientation="h",
        showlegend=False,
        marker_color='rgb(223,16,103)'
    ))
            
    def rgb(r, g, b):
        """
        RGB text (from @MiloCat's example)
        """
        return f"\033[38;2;{r};{g};{b}m"

    pink = rgb(223,16,103)

    reset = "\033[0m" # Important!
    title = f'This is black text {pink} this is a highlight {reset}.'
    print(title)
    
    fig.update_layout(
        title={"text": title},
    )

    fig.show()

df = pd.DataFrame({'col_name': ['A', 'B', 'C', 'D', 'E', 'F'], 'value':[123, 34, 54, 87, 98, 102]})
create_barchart(df)
