Question

为什么要创建两个图？我希望不要只创建两个图，而只能创建一个图。

import matplotlib.pyplot as pl

x=1,2,3,4
y=3,6,1,9
pl.plot(x, y)

pl.figure(figsize=(7.5, 5), dpi=80)
pl.axis([0,29,0,21])
pl.xticks([1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24]) 
pl.yticks([0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20])
pl.xlabel("Giornate", fontweight="bold")
pl.ylabel("Ore", fontweight="bold")
pl.title("Febbraio 2019", fontsize=20, fontweight="bold")
pl.grid(b=True, color="gray")
pl.rcParams['axes.facecolor'] = "tan"

pl.show()

Answer 1

这给了我一个。我更改了您要求绘图的线的位置。调用pl.figure和其他一些使您的绘图漂亮的参数后，请调用pl.plot。

import matplotlib.pyplot as pl

x=1,2,3, 4
y=3,6,1,9
pl.figure(figsize=(7.5, 5), dpi=80)
pl.axis([0,29,0,21])
pl.xticks([1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24]) 
pl.yticks([0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20])
pl.plot(x, y)
pl.xlabel("Giornate", fontweight="bold")
pl.ylabel("Ore", fontweight="bold")
pl.title("Febbraio 2019", fontsize=20, fontweight="bold")
pl.grid(b=True, color="gray")
pl.rcParams['axes.facecolor'] = "tan" 
pl.show()

Answer 2

调用pl.plot时创建第一个图形，调用pl.figure函数时创建第二个图形。

您需要将其中之一扔掉。

Answer 3

如果在调用plt.plot后使用plt.figure，则会创建第二个数字

import matplotlib.pyplot as pl

x=1,2,3,4
y=3,6,1,9


pl.figure(figsize=(7.5, 5), dpi=80)

pl.plot(x, y)

pl.axis([0,29,0,21])
pl.xticks([1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24]) 
pl.yticks([0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20])
pl.xlabel("Giornate", fontweight="bold")
pl.ylabel("Ore", fontweight="bold")
pl.title("Febbraio 2019", fontsize=20, fontweight="bold")
pl.grid(b=True, color="gray")
pl.rcParams['axes.facecolor'] = "tan"

pl.show()

Python matplotlib-两个图表而不是一个
