为什么 seaborn 中没有应用调色板？

Question

When plotting histplot, I can't apply the color palette, what's the problem? In other plottings, the palette works. Here is my code:

plt.figure(figsize=(15, 8))
sns.histplot(x='age', data=df, bins = 20)
sns.color_palette('plasma', as_cmap=True)
plt.show()

Thanks for the help.

You should specify the palette in the same visual:

plt.figure(figsize=(15, 8))
sns.histplot(x='age', data=df, bins = 20,palette='plasma')
plt.show()
