Question

I have two variables I want to plot on a scatter graph. I want one variable to be displayed in blue and the other in red. I only just started using Python, and I am rather confused.

Answer 1

scatter takes an argument color which allows you to set the point color (hard to guess).

x = linspace(0,10)
y1 = randn(50)
y2 = randn(50)+10

scatter(x, y1, color='red')
scatter(x, y2, color='blue')
