Python matplotlib - Two charts instead of one

Question

Why are two graphs created? I would like that instead of being created two separate graphs, only one was created.

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()

pl.figure(figsize=(7.5, 5), dpi=80) creates a new figure but you already called the plot command. Call pl.figure before you plot anything — Edgar H

First figure gets created when you call pl.plot and the second one gets created when you call pl.figure function.

You need to throw one of them out.

You just need to change the position; where you call pl.plot as following:

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()

If you use plt.figure after calling plt.plot a second figure is created

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()
