There are multiple types of Scatter Symbols available in the matplotlib package and can be accessed through the command marker. In this article, we will show some examples of different marker types and also present a list containing all the markers as defined by matplotlib.

matplotlib軟件包中有多種類型的散布符號 ，可以通過命令標記進行訪問。 在本文中，我們將顯示一些不同標記類型的示例，并提供一個包含由matplotlib定義的所有標記的列表。

Available Markers:

可用標記：

markers = {'.': 'point', ',': 'pixel', 'o': 'circle', 'v': 'triangle_down', 
'^': 'triangle_up', '': 'triangle_right', 
'1': 'tri_down', '2': 'tri_up', '3': 'tri_left', '4': 'tri_right', 
'8': 'octagon', 's': 'square', 'p': 'pentagon', '*': 'star', 
'h': 'hexagon1', 'H': 'hexagon2', '+': 'plus', 'x': 'x', 
'D': 'diamond', 'd': 'thin_diamond', '|': 'vline', '_': 'hline', 
'P': 'plus_filled', 'X': 'x_filled', 0: 'tickleft', 1: 'tickright', 
2: 'tickup', 3: 'tickdown', 4: 'caretleft', 5: 'caretright', 
6: 'caretup', 7: 'caretdown', 8: 'caretleftbase', 9: 'caretrightbase', 
10: 'caretupbase', 11: 'caretdownbase', 
'None': 'nothing', None: 'nothing', ' ': 'nothing', '': 'nothing'}

散點符號的Python代碼 (Python code for scatter symbol)

import matplotlib.pyplot as plt
import numpy as np
x = np.arange(0.0, 50.0, 2.0)
y = x ** 1.3 + np.random.rand(*x.shape) * 30.0
s = np.random.rand(*x.shape) * 300 + 500
plt.figure()
plt.scatter(x, y, s, c="y", alpha=0.7, marker='X',
label="Gold Mark")
plt.xlabel("Years")
plt.ylabel("Gold")
plt.title('Scatter Plot: Marker')
plt.legend()
plt.show()
plt.figure()
plt.scatter(x, y, s, c="b", alpha=0.5, marker='<',
label="Gold Mark")
plt.xlabel("Years")
plt.ylabel("Gold")
plt.title('Scatter Plot: Marker')
plt.legend()
plt.show()
plt.figure()
plt.scatter(x, y, s, c="g", alpha=0.5, marker='^',
label="Gold Mark")
plt.xlabel("Years")
plt.ylabel("Gold")
plt.title('Scatter Plot: Marker')
plt.legend()
plt.show()
plt.figure()
plt.scatter(x, y, s, c="r", alpha=0.5, marker='8',
label="Gold Mark")
plt.xlabel("Years")
plt.ylabel("Gold")
plt.title('Scatter Plot: Marker')
plt.legend()
plt.show()
plt.figure()
plt.scatter(x, y, s, c="g", alpha=0.5, marker='p',
label="Gold Mark")
plt.xlabel("Years")
plt.ylabel("Gold")
plt.title('Scatter Plot: Marker')
plt.legend()
plt.show()
