title: How to get selected bar x-axis value using MPAndroidChart?
body: <p>I am using the <a href="https://github.com/PhilJay/MPAndroidChart" rel="nofollow noreferrer">MPAndroidChart</a> library in my Android graphs app and I need to display the dialog with a title containing the selected bar's x-axis values. </p>
  
  <p>I referred to this <a href="https://github.com/PhilJay/MPAndroidChart/wiki/Interaction-with-the-Chart" rel="nofollow noreferrer">wiki entry</a> for click events to the bars in the bar graph. But now I need to get the selected bar x-axis value as a title. Can any one tell me how to achieve it?</p>
