ValueError:尝试在饼图上设置颜色时无效的RGBA参数

Question

我正在尝试使用三个字典创建一个饼状图，并使用指定的颜色代码为标签着色，这些是我的字典:

这是我创建piechart的尝试:

from collections import Counter
language_counts = Counter(language_families.values())
colors = [dict_langfam2color[fam] for fam in language_counts.keys()]
plt.pie(language_counts.values(), labels=language_counts.keys(), autopct='%1.1f%%', colors=colors)
plt.show()

问题是，我不断得到这个错误:ValueError:无效的RGBA参数:'(153,153,0)'，有人知道吗?

Answer 1

您不仅需要摆脱引号，而且还需要将dict_langfam2color中的颜色值转换为matplotlib所期望的格式，即0-1范围内的浮点数(@JohanC提到的):

格式	示例
RGB或RGBA (red, green, blue, alpha)元组浮点值在封闭区间[0,1]。(0.1, 0.2, 0.5) (0.1, 0.2, 0.5, 0.3)
