MPAndroidChart HorizontalBarChart setVisibleXRangeMaxmum not working

Question

According to the photo. I'm using HorizontalBarChart in MPAndroidChart. I just want let the chart show about 10 items in x direction of HorizontalBarChart. I setVisibleXRangeMinimum and setVisibleXRangeMaxmum but it not working. What should i do to make it work???

• initialization

  private void initCombinedChart() {
      horizontalBarChart.setDescription("");
      horizontalBarChart.setDrawGridBackground(false);
      horizontalBarChart.setDrawBarShadow(false);
      horizontalBarChart.getLegend().setTextColor(Color.rgb(255, 255, 255));
      horizontalBarChart.setScaleEnabled(false);
      horizontalBarChart.setOnChartValueSelectedListener(this);
      horizontalBarChart.setDrawValueAboveBar(true);
  
      Legend legend = horizontalBarChart.getLegend();
      legend.setFormSize(8f);
  
      YAxis rightAxis = horizontalBarChart.getAxisRight();
      rightAxis.setEnabled(false);
  
      YAxis leftAxis = horizontalBarChart.getAxisLeft();
      leftAxis.setDrawGridLines(false);
      leftAxis.setAxisMinValue(0f);
      leftAxis.setTextColor(Color.rgb(255, 255, 255));
      leftAxis.setEnabled(false);
  
      XAxis xAxis = horizontalBarChart.getXAxis();
      xAxis.setPosition(XAxis.XAxisPosition.BOTTOM_INSIDE);
      xAxis.setDrawGridLines(false);
      xAxis.setDrawAxisLine(false);
  
  }
  

• setData

  private void setData() {
      ArrayList<BarEntry> entries = new ArrayList<BarEntry>();
      ArrayList<String> xVals = new ArrayList<>();
      DateHelper dateHelper = new DateHelper(DateHelper.FORMAT_ONLINE);
  
      for (OnlineCountResult.OnlineCountModel model : mDatas) {
          xVals.add(dateHelper.getDateSimpleDate(model.getBatchMinute()));
          entries.add(new BarEntry((float) model.getCountNum(), mDatas.indexOf(model)));
      }
  
      BarDataSet set;
  
      if (horizontalBarChart.getData() != null && horizontalBarChart.getData().getDataSetCount() > 0) {
          set = (BarDataSet) horizontalBarChart.getData().getDataSetByIndex(0);
          set.setYVals(entries);
          horizontalBarChart.getData().setXVals(xVals);
          horizontalBarChart.getData().notifyDataChanged();
          horizontalBarChart.notifyDataSetChanged();
      } else {
          ...
  
          ArrayList<IBarDataSet> dataSets = new ArrayList<>();
          dataSets.add(set);
  
          BarData data = new BarData(xVals, dataSets);
          data.setValueTextSize(20f);
  
          horizontalBarChart.setData(data);
          horizontalBarChart.setVisibleXRangeMaximum(10);
          horizontalBarChart.setVisibleXRangeMinimum(7);
  
          horizontalBarChart.animateY(1000);
      }
  }
  

Answer 1

The problem is, you are setting the dataset to chart and then you are setting its X Range instead of setting X Range before setting the dataset to chart.

You can add either following code in else part at the end:

horizontalBarChart.invalidate();
horizontalBarChart.refreshDrawableState();

Or following code in your initCombinedChart:

horizontalBarChart.setVisibleXRangeMaximum(10);
horizontalBarChart.setVisibleXRangeMinimum(7);

Edit 1: Try with setVisibleYRangeMaximum instead of setVisibleXRangeMaximum.
