title: Add padding on first and last label on x-axis in MPAndroidChart
body: <p>I am using a Scatter Chart (<a href="https://github.com/PhilJay/MPAndroidChart" rel="noreferrer">MPAndroidChart library</a>) and it looks like below presently.<a href="https://i.stack.imgur.com/6EKCT.png" rel="noreferrer"><img src="https://i.stack.imgur.com/6EKCT.png" alt="enter image description here"></a></p>
  
  <p>Everything works well so far except for the values on the first and last label (Su and S) wherein the circles are cut off. Is there a way to add padding so that Su has some padding on the left on the X Axis and renders the circle completely and S has some padding on the right so the circle values for S render completely. I have tried to manually set padding going through numerous examples but nothing has worked correctly so far. Is someone has any ideas and can point in the right direction it will be great.. Thanks!</p>
