title: MPAndroidChart adding and display bar chart label
body: <p>Just started using the <a href="https://github.com/PhilJay/MPAndroidChart" rel="nofollow noreferrer">MPAndroidChart</a> version 3.0.0 beta and i have created a project that can show my values in a bar chart. My question is where do i add and display labels.
  Each Bar should have its own label eg. "Flue", "Cheese" etc at the bottom. Not sure what function does this, am actively searching and reading the Docs/Wiki but no joy currently. </p>
