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.xticks(rotation = 0)
plt.xlabel('nutrient')
plt.ylabel('%')
plt.title('nutrient vs mineral')
plt.grid(axis = 'y')
plt.legend(loc = 'best')
