Python Matplotlib scatter plot: specify color points depending on difference between X & Y:

Question

I want to color points uniquely only if there is a difference between the x & y values (eg abs(x - y) > 10).

How can I do that?

num = 1000
x = np.linspace(0,100, num = num)
y = np.random.normal(size = num)

plt.scatter(x, y, c='r', edgecolors='black')
plt.gca().spines['right'].set_color('none')
plt.gca().spines['top'].set_color('none')
plt.show()

Answer 1

You can create a color vector based on the cut off rule such as

plt.scatter(x, y, c=np.where(np.abs(xy)>10, 'g', 'b'), edgecolors='black')
