Question:

Is it possible to turn off "corner rounding" when using plot in matplotlib?

Setup:

• I am trying to present a complicated nonsmooth function in a presentation.
• As a default (understandably) matplotlib rounds corners. (This is especially visible when the linewidth is increased.)
• I need more linewidth so the plot can be seen when the figure is projected.

Example:

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(-1, 1, 1001)
y = abs(x)
plt.plot(x, y, linewidth=10)

plt.show()

produces the image:

Attempts:

• Increasing the number of points in x does not resolve this issue.
• Note that the point x=0 is included in the plot.

Summary:

The plotted curve above appears rounded at x=0 when the function is not.
