我想從數據庫獲取 xAxis，這是不同查詢的結果，以便我的圖表可以動態顯示數據。對于靜態 mpchart 我對此沒有問題。我在onCreate中調用了這個函數。private void drawChart(){    getChartData();    BarDataSet barDataSet1 = new BarDataSet(sehat(), "Sehat");    BarDataSet barDataSet2 = new BarDataSet(sakit(), "Sakit");    barDataSet1.setColor(Color.BLUE);    barDataSet2.setColor(Color.RED);    chart.getXAxis().setDrawGridLines(false);    chart.getAxisLeft().setDrawGridLines(false);    chart.getDescription().setEnabled(false);    BarData barData = new BarData(barDataSet1, barDataSet2);    chart.setData(barData);    String[] area = new String[]{"UT PBRK", "POOL SLI", "UT TJR", "UT TRD", "UTR BATAKAN", "UT PBLP", "UT PBPN"};    XAxis xAxis = chart.getXAxis();    xAxis.setValueFormatter(new IndexAxisValueFormatter(area));    xAxis.setCenterAxisLabels(true);    xAxis.setPosition(XAxis.XAxisPosition.BOTTOM);    xAxis.setGranularity(1);    xAxis.setGranularityEnabled(true);    chart.setDragEnabled(true);    chart.setVisibleXRangeMaximum(3);    float barSpace = 0.08f;    float groupSpace = 0.54f;    barData.setBarWidth(0.15f);    chart.getXAxis().setAxisMinimum(0);    chart.getXAxis().setAxisMaximum(0+chart.getBarData().getGroupWidth(groupSpace, barSpace)*7);    chart.getAxisLeft().setAxisMinimum(0);    chart.groupBars(0, groupSpace, barSpace);    chart.invalidate();}private ArrayList<BarEntry> sakit() {        ArrayList<BarEntry> dataEntries = new ArrayList<>();        dataEntries.add(new BarEntry(1, 2));        dataEntries.add(new BarEntry(2, 1));        dataEntries.add(new BarEntry(3, 1));        dataEntries.add(new BarEntry(4, 4));        dataEntries.add(new BarEntry(5, 3));        dataEntries.add(new BarEntry(6, 7));        dataEntries.add(new BarEntry(7, 7));        return dataEntries;    }我要使這條線變得動態。String[] area = new String[]{"UT PBRK", "POOL SLI", "UT TJR", "UT TRD", "UTR BATAKAN", "UT PBLP", "UT PBPN"};到目前為止，我已經嘗試了一些我在谷歌中找到的實驗。這個更接近。Log.d顯示結果數據。但是當我使用 String[] 時，它不會顯示在我的圖表中。
