I am showing several LineDataSet in my chart. I don't need to show circles by default. But when user clicks a chart I need to show circles on all lines depending x value. How to implement it?

First you need to set draw circles false with your dataset as follows:

lineDataSet.setDrawCircles(false);

After that you need to implement OnChartGestureListener() as follows:

 lineChart.setOnChartGestureListener(new OnChartGestureListener()
 
 @Override
 public void onChartTranslate(MotionEvent me, float dX, float dY) 
 // TODO Auto-generated method stub

 

 @Override
 public void onChartSingleTapped(MotionEvent me)
 
 // TODO Auto-generated method stub
 if(lineDataSet.isDrawCirclesEnabled())
 
 lineDataSet.setDrawCircles(false);
 
 else
 
 lineDataSet.setDrawCircles(true);
 
 

 @Override
 public void onChartScale(MotionEvent me, float scaleX, float scaleY) 
 // TODO Auto-generated method stub

 

 @Override
 public void onChartGestureStart(MotionEvent me, ChartTouchListener.ChartGesture lastPerformedGesture) 

 

 @Override
 public void onChartGestureEnd(MotionEvent me, ChartTouchListener.ChartGesture lastPerformedGesture) 

 

 @Override
 public void onChartLongPressed(MotionEvent me) 
 // TODO Auto-generated method stub

 

 @Override
 public void onChartFling(MotionEvent me1, MotionEvent me2,
 float velocityX, float velocityY) 
 // TODO Auto-generated method stub

 

 @Override
 public void onChartDoubleTapped(MotionEvent me) 
 // TODO Auto-generated method stub

 
 );

This will do the job. Best of luck bro !
