Your solution is here

Because the MPchart Can't set his description by String.

Description description = new Description();
description.setText("Add Your string here");
chart.setDescription(description);

You can set BarData like below code :

BarDataSet set1;
set1 = new BarDataSet(xValue, "");
set1.setDrawIcons(true);
set1.setStackLabels(new String[]{"Male", "Female"});
set1.setDrawValues(true);
set1.setValueTextSize(12f);
set1.setColors(ColorTemplate.JOYFUL_COLORS);

BarData data1 = new BarData(set1);
data1.setBarWidth(15f);
positiveChart.setData(data1);
positiveChart.setFitBars(true);
positiveChart.invalidate();
