How to show labels on right and values to left side in HorizontalBarChart?

Question

Drawing a horizontal bar chart using MPAndroidChart 3.0.2. the values are shown on the right of the bars. I could use setValueFormatter and use IAxisValueFormatter interface

Answer 1

I implemented something similar just a few days back. Here's the code...

public class MainActivity extends AppCompatActivity {

    protected HorizontalBarChart mChart;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ArrayList<String> labels = new ArrayList<>();
        labels.add("January");
        labels.add("February");
        labels.add("March");
        labels.add("April");
        labels.add("May");
        labels.add("June");

        mChart = (HorizontalBarChart) findViewById(R.id.barChart);
        mChart.setDrawBarShadow(false);
        mChart.setDrawValueAboveBar(true);
        mChart.getDescription().setEnabled(false);
        mChart.setPinchZoom(false);
        mChart.setDrawGridBackground(false);


        XAxis xl = mChart.getXAxis();
        xl.setPosition(XAxis.XAxisPosition.BOTTOM);
        xl.setDrawAxisLine(true);
        xl.setDrawGridLines(false);
        CategoryBarChartXaxisFormatter xaxisFormatter = new CategoryBarChartXaxisFormatter(labels);
        xl.setValueFormatter(xaxisFormatter);
        xl.setGranularity(1);

        YAxis yl = mChart.getAxisLeft();
        yl.setPosition(YAxis.YAxisLabelPosition.INSIDE_CHART);
        yl.setDrawGridLines(false);
        yl.setEnabled(false);
        yl.setAxisMinimum(0f);

        YAxis yr = mChart.getAxisRight();
        yr.setPosition(YAxis.YAxisLabelPosition.INSIDE_CHART);
        yr.setDrawGridLines(false);
        yr.setAxisMinimum(0f);

        ArrayList<BarEntry> yVals1 = new ArrayList<BarEntry>();
        for (int i = 0; i < 6; i++) {
            yVals1.add(new BarEntry(i, (i+1)*10));
        }

        BarDataSet set1;
        set1 = new BarDataSet(yVals1, "DataSet 1");
        ArrayList<IBarDataSet> dataSets = new ArrayList<IBarDataSet>();
        dataSets.add(set1);
        BarData data = new BarData(dataSets);
        data.setValueTextSize(10f);
        data.setBarWidth(.9f);
        mChart.setData(data);
        mChart.getLegend().setEnabled(false);
    }

    public class CategoryBarChartXaxisFormatter implements IAxisValueFormatter {

        ArrayList<String> mValues;

        public CategoryBarChartXaxisFormatter(ArrayList<String> values) {
            this.mValues = values;
        }

        @Override
        public String getFormattedValue(float value, AxisBase axis) {

            int val = (int) value;
            String label = "";
            if (val >= 0 && val < mValues.size()) {
                label = mValues.get(val);
            } else {
                label = "";
            }
            return label;
        }
    }

}

Hope this helps.
