I can t get a graph out of my information

Question

plt.subplot(3, 2, 1)
plt.scatter(child[child.Sex=='FEV (litres)']['female'], child[child.Sex=='FEV (litres)']['male'],label='Smoker',color='purple' )
plt.xlabel('female')
plt.ylabel('male')
plt.title('Smoker')
plt.subplot(3,2,2)
plt.scatter(child[child.Smoker=='FEV (litres)']['none'],child[child.Smoker=='FEV (litres)']['smoker'], marker='P')
plt.xlabel('non')
plt.ylabel('smoker')
plt.title('Smokers')

Hi@lzzy,

According to your error, there is a problem with your data set. You may have unwanted space or comma in your female column. Try to check your schema properly and remove the unwanted characters. It will work.
