Group | Man | Women

0 to 4|10000|20000
5 to 9|20000|50000
...
80+   |100  |4000

and a need to plot a bar graph, but when define the x and y and put the code plt.plot(x,y)

python returs the error unhashable type: 'numpy.ndarray' ,

how can I resolve?

Answer 1

You can write to make bar chart with matplotlib:

import pandas as pd
import matplotlib.pyplot as plt
file = pd.read_csv('tmp.csv', sep=';', header=0)
plt.barh(file["Group"].tolist(), file["Men"].tolist())
plt.show()

or the below as alternative:

import pandas as pd
import matplotlib.pyplot as plt
file = pd.read_csv('tmp.csv', sep=';', header=0)
ax = file.plot.barh(x='Group', y='Women')
plt.show()
