In Matplotlib, markerthe parameters of the Axes object refer to the shape of the marker (such as the point in the scatter plot) in the drawing graph. It can be a string or special characters, for example:
'.': dots',': pixel'o': round'v': lower triangle'^': upper triangle'<': left triangle'>': right triangle'1': play tricks'2': Shanghuaxin'3': left hand'4': right flower heart's': square'p': pentagon'*': star'h': hexagon 1'H': Hexagon 2'+': Cross'x': x shape'D': rhombus'd': narrow rhombus
For example, when using the functions in the Matplotlib library scatter()to draw a two-dimensional scatter plot, you can markerchange the shape of the scatter by setting parameters. For example, the following code will draw red star points:
import matplotlib.pyplot as plt
x = [1, 2, 3, 4, 5]
y = [10, 8, 6, 4, 2]
plt.scatter(x, y, c='red', marker='*', s=50)
plt.show()
operation result:
