将包含元组的列表绘制到图形中

Question

我有一个元组列表，例如

[("name1",0.05),("name2",0.034),("name3",0.03)....] 

我想用这些点的一行制作一个图表

y0 = 0.05
y1 = 0.034 

和

x0 = "name1"
x1 = "name2" 

等等。

我怎么能在python / sage中这样做？

Answer 1

import matplotlib.pyplot as plt
import numpy as np

x = np.array([0,1,2,3])
y = np.array([20,21,22,23])
my_xticks = ['John','Arnold','Mavis','Matt']
plt.xticks(x, my_xticks)
plt.plot(x, y)
plt.show()

帮了我很多忙
