如何使用 Matplotlib 显示折线图的阴影？

Question

I am trying to make a drop shadow for some data I have. View the current image here

I can't increase the drop shadow's width. Is there a way to do it?

Here's what I currently have:

plt.plot(times, past_values,color='red',path_effects=[path_effects.SimpleLineShadow(shadow_color="red"),path_effects.Normal()])

Answer 1

You need to pass the linewidth argument to SimpleLineShadow .

plt.plot(times, past_values,color='red',path_effects=[path_effects.SimpleLineShadow(shadow_color="red", linewidth=5),path_effects.Normal()])

Answer 2

You can simple add shadow=True Here is an example

plt.plot(times, past_values,color='red',shadow=True)

Try it it may work

Answer 3

import matplotlib.pyplot as plt
import numpy as np
from matplotlib.patheffects import PathPatchEffect, SimpleLineShadow, Normal
sns.set()

plt.plot([1,2,3],[1,4,9],color='red',path_effects=[SimpleLineShadow(shadow_color="red", linewidth=10),Normal()])
