float value

    xAxis.setValueFormatter(new IAxisValueFormatter() {
        @Override
        public String getFormattedValue(float value, AxisBase axis) {
            try {
                return xVals.get((int) (value / 10));//dividing the value by 10 to get the multiplied value.
            } catch (Exception e){
                return "";
            }
        }
    });
