Mpandroidchart: DataSet values not appearing on Horizontal Bar Chart

[fxhereng]

I would like to show the values at the end of each bar, but i can't get it work. Here is my code:

    /**
     * Set up horizontal barchart for polls stats
     * @param totals
     */
    private void setUpPollBarChart(int[] totals) {
        barChart.setDescription(""); 
        barChart.setMaxVisibleValueCount(maxValueCount);
        barChart.setPinchZoom(false);
        barChart.setDrawGridBackground(false); //Do not display grid background

        //Disable all interaction with the chart
        barChart.setDrawHighlightArrow(false);
        barChart.setHighlightPerTapEnabled(false);
        barChart.setHighlightPerDragEnabled(false);
        barChart.setDoubleTapToZoomEnabled(false);


        //Disable surroundings graphs (axis and legends)
        XAxis xAxis = barChart.getXAxis();
        xAxis.setEnabled(false);
        YAxis leftAxis = barChart.getAxisLeft();
        YAxis rightAxis = barChart.getAxisRight();
        leftAxis.setEnabled(false);
        rightAxis.setEnabled(false);
        Legend l = barChart.getLegend();
        l.setEnabled(false);

        //Set data
        ArrayList<BarEntry> yVals = new ArrayList<BarEntry>();
        ArrayList<String> xVals = new ArrayList<String>();

        for (int i=0; i < totals.length; i++) {
            xVals.add(String.valueOf(i));
            yVals.add(new BarEntry(StatisticsUtils.getNormalizedValue(totals, i),(totals.length-1) - i)); 
        }

        BarDataSet dataSet = new BarDataSet(yVals,"dataSet polls");
        dataSet.setDrawValues(true); // This doesn't seem to work
        dataSet.setValueTextColor(Color.BLACK);
        dataSet.setValueTextSize(12f);
        dataSet.setColors(new int[]{R.color.colorRedDark}, getContext());
        dataSet.setBarSpacePercent(StatisticsUtils.BAR_SPACE_PERCENT);

        BarData data = new BarData(xVals, dataSet);
        data.setDrawValues(true);  // just in case
        data.setValueTextSize(11f);
        data.setValueTextColor(Color.BLACK);

        horizontalBarChart.setData(data);
    }

(the red top one)

I'm using the 2.1.6, I already tried reinstalling the app.

What am I missing?

Call chart.invalidate()

see here: http://stackoverflow.com/questions/34263475/mpandroidchart-is-not-updating/34264238#34264238

Thank you for answering quickly, I finally found the problem, the invalidate() didn't change anything there, it was the setMaxVisibleValueCount() that was causing trouble.

Hi,

What was the issue, i am also facing same issue. How you resolved this issue.

facing the same issue here with HorizontalBar , what is the root cause? how could i get it fixed? already checked with invalidate() , but that doesn't work. Please, help.

Hello All,
I have been trying to add months to my barchart and plot rating against them. However, all the months don't display. Could you please help

i am also facing same issue(DataSet values not appearing on Horizontal Bar Chart).
i resolved this issue by setAxisMinimum.

YAxis left = horizontalBarChart.getAxisLeft();
left.setAxisMinimum(0f);
