将垂直虚线和虚线添加到LineChart (mpandroidchart)

// 获取LineChart的引用
LineChart lineChart = findViewById(R.id.lineChart);

// 创建数据集合
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));

// 创建LineDataSet对象
LineDataSet dataSet = new LineDataSet(entries, "数据集");
dataSet.setColor(Color.BLUE);
dataSet.setLineWidth(2f);
dataSet.setCircleColor(Color.RED);
dataSet.setCircleRadius(4f);
dataSet.setDrawValues(true);

// 创建LineData对象并设置数据集合
LineData lineData = new LineData(dataSet);

// 设置LineChart属性
lineChart.setData(lineData);
lineChart.getDescription().setText("数据趋势图");
lineChart.getXAxis().setPosition(XAxis.XAxisPosition.BOTTOM);
lineChart.getAxisRight().setEnabled(false);

// 添加垂直虚线
LimitLine limitLine = new LimitLine(3f, "垂直虚线");
limitLine.setLineColor(Color.GREEN);
limitLine.setLineWidth(2f);
limitLine.enableDashedLine(10f, 10f, 0f);
lineChart.getXAxis().addLimitLine(limitLine);

// 添加虚线
YAxis yAxis = lineChart.getAxisLeft();
LimitLine limitLine2 = new LimitLine(5f, "虚线");
limitLine2.setLineColor(Color.YELLOW);
limitLine2.setLineWidth(2f);
limitLine2.enableDashedLine(10f, 10f, 0f);
yAxis.addLimitLine(limitLine2);

// 刷新图表
lineChart.invalidate();
