plot a scatter graph for a dictionary

Question

Please I need help I want to plot a graph using

pandas.dataframe.plot(kind='scatter' , x=x , y=y )

for a dictionary type {'2022-01-30': 50, '2022-01-31': 152, '2022-02-01': 41 }

Please how can I use dictionary since i need a title

It is giving me the error x is not defined x is the key and y is the value

but on the graph x should be 'Date' and y should be 'Quantity'

Answer 1

You have to create a DataFrame first:

import pandas as pd
import matplotlib.pyplot as plt

data = {'2022-01-30': 50, '2022-01-31': 152, '2022-02-01': 41}
df = pd.Series(data, name='y').rename_axis('x').reset_index()
df.plot(kind='scatter', x='x', y='y')
plt.show()

Output:

Answer 2

You can't plot a dict type with a dataframe function. Thus two possibilities :

• use your dictionnary and follow Plot a scatter plot in python with matplotlib with dictionary (use of matplotlib.pyplot.scatter)

• convert your dictionnary to dataframe with pd.DataFrame.from_dict(data) and then use pandas.DataFrame.plot.scatter(x=x, y=y)

Answer 3

Just take out the keys & values

import matplotlib.pyplot as plt

data = {'2022-01-30': 50, '2022-01-31': 152, '2022-02-01': 41}
x, y = data.keys(), data.values()

plt.scatter(x, y)
