如何在MP android折线图中突出显示特定的数据点？

implementation 'com.github.PhilJay:MPAndroidChart:v3.1.0'

<com.github.mikephil.charting.charts.LineChart
    android:id="@+id/chart"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

LineChart chart = findViewById(R.id.chart);
chart.setDrawGridBackground(false);
chart.getDescription().setEnabled(false);
chart.setTouchEnabled(true);
chart.setDragEnabled(true);
chart.setScaleEnabled(true);

ArrayList<Entry> entries = new ArrayList<>();
entries.add(new Entry(0, 4));
entries.add(new Entry(1, 8));
entries.add(new Entry(2, 6));
entries.add(new Entry(3, 2));
entries.add(new Entry(4, 7));

LineDataSet dataSet = new LineDataSet(entries, "Data Set");

dataSet.setColor(Color.BLUE);
dataSet.setCircleColor(Color.RED);
dataSet.setCircleRadius(8f);
dataSet.setDrawCircleHole(false);
dataSet.setDrawValues(false);

// 设置需要突出显示的数据点
dataSet.setHighlightEnabled(true);
dataSet.setHighLightColor(Color.YELLOW);
dataSet.setHighlightLineWidth(2f);
dataSet.setDrawHorizontalHighlightIndicator(false);

LineData lineData = new LineData(dataSet);
chart.setData(lineData);

chart.invalidate();
