python - Matplotlib/Seaborn 中的颜色无法正常工作

Question

我目前正在使用 Jupyter Notebooks 和 Python 3.6。我的 Matplotlib 版本 = 2.1.0 和 Seaborn = 0.8。

我正在尝试创建一个简单的直方图，但我选择的颜色没有正确显示。我已经尝试过名称和十六进制代码，但它们仍然关闭。当我运行下面的命令时，如果它呈浅紫色。这是一个错误吗？

Answer 1

您看到的颜色实际上是您指定的颜色的透明版本。要将透明度设置回不透明，请将 alpha=1 添加到直方图参数。

fig = sns.distplot(df['Amt'],kde=False, bins=50 , color='darkblue',  
                   hist_kws=dict(edgecolor="black", linewidth=2, alpha=1))
