Add to this the code for generating a grid on the chart, as well as specifying the percentage difference directly on the chart bars plt.figure(figsize = (12, 4)) plt.bar(data.index, data['nutri'], color = 'darkblue', label = 'nutri') plt.bar(data.index, data['mineral'], color = 'brown', label = 'mineral')

plt.title('Percentage difference between nutrient and mineral content for each vegitable')
plt.xlabel('Vegetable')
plt.ylabel('Percentage difference')
plt.legend()
plt.show()
