Question

I want to add my bar values to the left of the bar and the bar labels to the right of the bar.

Below is the code that initiliz

Answer 1

Yes, this is definitely possible using the ValueFormatter and AxisValueFormatter interfaces.

1. Create a formatter that adds the labels to the right of your bars:

   public class LabelFormatter implements ValueFormatter {
       @Override
       public String getFormattedValue(float value, Entry entry, int dataSetIndex, ViewPortHandler viewPortHandler) {
           // assuming that getHeader() returned the label
           return (String) entry.getData();
       }
   }
   

2. Create an axis formatter that adds the values to the left of your bars:

   public class BarValueFormatter implements AxisValueFormatter {
       private final DataSet mData;
   
       public BarValueFormatter(DataSet data) {
           mData = data;
       }
   
       @Override
       public String getFormattedValue(float value, AxisBase axis) {
           return String.valueOf((int) mData.getEntryForXPos(value, DataSet.Rounding.CLOSEST).getY());
       }
   }
   

3. Set your formatters to the dataset and axis:

   set1.setValueFormatter(new LabelFormatter());
   mChart.getXAxis().setValueFormatter(new BarValueFormatter(set1));
   

Note that you need to remove the call to xl.setDrawLabels(false); for the x-axis, so the values are properly rendered.
