Legands du graphique à bulles Python - TypeError

Question 1

Voici mon code:

import pandas
import matplotlib.pyplot as plt
import matplotlib.patches as mpatches

%matplotlib inline

pandas.set_option ('max_columns',10)

df= pandas.read_csv('C:/Users/HP/Desktop/Coding/Python/2.Python Data Analysis/Module 2- Python Data Visualization/M2-Bubble Chart with Labels and Legend data.csv')

plt.scatter(x=df['GDP per Capita'],y=df['Life Span'],s=df['Population']/1000, alpha=0.5, c=df['Bubble color'])
            #alpha at 0.5 to set the transparency 



#chart title, axis labels 
plt.title('GDP,Lifespan,Population (Bubble size)')
plt.xlabel(' GDP')
plt.ylabel('Lifespan')

#bubble labels 
x,y= df['GDP per Capita'],df['Life Span']
for i, txt in enumerate (df['Territory']):
    plt.annotate(txt,(x[i],y[i]))
    print(i,txt,x[i],y[i],df['Population'][i],df['Bubble color'][i])
#annotate: is used to assign the population with the chart sp have from text, the x and y will be the next one 
#it will print out the index number with the one that assigned with it as well 


#legend 
territory_list=list(df['Territory'])
bubble_color_list = list(df['Bubble color'])
l = []
for i in range (0,len(df.index)):
        l.append(mpatches.Patch(color=bubble_color_list[i],
                               alpha=0.5,
                               label=territory_list[i]))





plt.legend(handles=1,loc=(2,0))   
#the i is in the For loop is just basically like the one above to have all the information

Je cherche à générer un graphique à bulles avec une légende pour cela, mais d'une certaine manière, il ne montre pas la légende comme il le suppose, juste le graphique, puis affiche ce message.

`TypeError: 'int' object is not iterable`

Qu'est-ce que je fais mal?

python r pandas dataframe matplotlib

Answer

Vous ne pouvez pas avoir handles=1 dans plt.legend(handles=1,loc=(2,0)).

handles doit être un conteneur, tel qu'une liste, un tuple, etc ...

Non seulement cela, mais un conteneur d'entiers inacceptable. N'écrivez pas handles=[1, 2, 3]

Le code suivant montre comment appeler correctement la méthode legend:

import numpy as np
import matplotlib.pyplot as plt

# Make some fake data.
a = b = np.arange(0, 3, .02)
c = np.exp(a)
d = c[::-1]


fig, ax = plt.subplots()
line1 = ax.plot(a, c, 'k--')
line2 = ax.plot(a, d, 'k:')
line3 = ax.plot(a, c + d, 'k')

ax.legend((line1, line2, line3), ('line 1', 'line 2', 'line 3'), loc=(2,0))

plt.show()
