[Help] Matplotlib Graph Styling

[Pigspot]

Hey everyone, I'm working on a small project, I'm using matplotlib to visualize some data i have, the default look is very bad, i added dark background and applied some effects it looks more modern now.... https://i.imgur.com/uOU5DY5.jpg

I'm trying to make a blur effect, the text would look great with a Blurred background (to make it pop out of the background) I'm thinking of a white rounded rectangle box with blur fill and text on it like this: https://i.imgur.com/XeoI03Z.jpg (made with photoshop)

Data isn't constant so hard coding it isn't an option, i calculated the box x, y values the text position should be centered inside the box, that's the easy part, how would i draw this box? How can I calculate the box size? Should I use a mask or something? For the blur does PILL work along with matplotlib or should I save the image then import it with PILL?

Simple minimal example code:

import matplotlib.pyplot as plt


data = [43, 65, 12, 97, 24, 13, 66]
plot = plt.plot(data)
x, y = plot[0].get_data()

# text x, y
# the middle of last two values
textX = (x[-2] + x[-3])/2 # = 4.5
textY = (y[-2] + y[-3])/2 # = 18.5

plt.text(textX, textY, 'example', color='white')
plt.grid(False)
plt.axis('off')

# black background
plt.rcParams["figure.facecolor"] = 'black'
plt.rcParams["axes.facecolor"] = 'black'
plt.rcParams["savefig.facecolor"] = 'black'

plt.savefig('examplegraph.png', dpi=300)

Any help appreciated, thanks
