Fill between two vertical lines in matplotlib
...
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
ax.plot(range(20))
ax.axvspan(8, 14, alpha=0.5, color='red')
plt.show()

How can I make an svg scale with its parent container?
...you have the following:
<svg>
<polygon fill=red stroke-width=0
points="0,10 20,10 10,0" />
</svg>
It will render as a 10px by 20px triangle:
Now, if you set only the width and height, that will change the size of the SVG element, but not scale the triangle:
...
autolayout - make height of view relative to half superview height
...ttribute inspector:
Then you can adjust the multiplier. If you want it 50% of the super view leave it at 1, since it is aligned per the super's center. This is also a great way to create views that are other percentages too (like 25% of super view)
