How to set different colors on label text in pandas pie chart-CodePudding

I would like to change the label colors for each part of the pie chart in accordance with the color of the section. I find questions doing it with matplotlib (see Different colors for each label in my pie chart). In my case I would like to do it using the creation of the plot with pandas. Is there a way to create the pie chart with pandas and then access the text of each label to change the color? Below is an example of my simplified code for which I would like to add a part modifying the colors as it is done in the link above.

    index_data = ["AAA", "BBB", "CCC", "DDD"]
    data = [10,20,20,40]
    df = pd.DataFrame(data=data,index=index_data,columns=['col1'])

    color_list = ['#FF7800','#73B22D','#5F5D60','#803C00']

    fig, ax = plt.subplots(figsize=(9,9))

    df.plot(kind='pie', ax=ax, y=df.columns[0], legend=False, label='', colors=color_list, autopct='%1.1f%%', textprops={'fontsize': 17})

    # --- I want to change colors here --- #

    plt.show()

Do you have any ideas ? Thanks

CodePudding user response：

You can get axis by assigning df.plot() to ax and then get texts attribute from ax as below:

index_data = ["AAA", "BBB", "CCC", "DDD"]
data = [10,20,20,40]
df = pd.DataFrame(data=data,index=index_data,columns=['col1'])

color_list = ['#FF7800','#73B22D','#5F5D60','#803C00']

fig, ax = plt.subplots(figsize=(9,9))

ax = df.plot(kind='pie', ax=ax, y=df.columns[0], legend=False, label='', colors=color_list, autopct='%1.1f%%', textprops={'fontsize': 17})

for text, color in zip(ax.texts, color_list):
    text.set_color(color)

plt.show()
