I want to draw a scattered plot using python. I have these two 2D arrays and I want to show them in same scattered plot.
[[69, 72], [72, 80], [74, 81], [70, 75], [78, 87], [71, 73], [69, 70], [71, 77]]
[[78, 139], [80, 158], [85, 154], [72, 105], [84, 148], [74, 87], [73, 106], [71, 109]]
How can I do this? I want points of different arrays to be of different colors. I'm using python 3.x
You can use Matplotlib scatter tool to graph your points. Here is how you'll do it, applying their example:
import matplotlib.pyplot as plt
import matplotlib
array1 = [[69, 72], [72, 80], [74, 81], [70, 75], [78, 87], [71, 73], [69, 70], [71, 77]]
array2 = [[78, 139], [80, 158], [85, 154], [72, 105], [84, 148], [74, 87], [73, 106], [71, 109]]
x1 = [point[0] for point in array1]
y1 = [point[1] for point in array1]
x2 = [point[0] for point in array2]
y2 = [point[1] for point in array2]
s = 20
plt.scatter(x1, y1, s, c="r", alpha=0.5, marker=r'o',
label="Array 1")
plt.scatter(x2, y2, s, c="b", alpha=0.5, marker=r'o',
label="Array 2")
plt.xlabel("X")
plt.ylabel("Y")
plt.legend(loc=0)
plt.show()
This will give you this nice looking graph:
