我正在开发一个需要实现折线图的应用程序。
为此，我正在使用 Achart 引擎绘制折线图，但我想使用一些示例坐标绘制垂直线，但我未能实现。但是我可以画水平线，但不能画垂直直线。
int[] x = { 1,2,3,4,5,6,7,8 };
int[] systolic = { 90,90,100,70,90,100,110,70};
//int[] systolic = { 90,90,90,90,90,90,90,90};
/* int[] diastolic = {70, 60, 65, 70, 45, 60, 70, 90 };
int[] pulse = {45, 60, 45, 80, 65, 50, 90, 70};*/
// Creating an XYSeries for Income
XYSeries systolicSeries = new XYSeries("Systolic");
// Creating an XYSeries for Expense
XYSeries diastolicSeries = new XYSeries("Diastolic");
// Creating an XYSeries for Expense
XYSeries pulseSeries = new XYSeries("Pulse");
// Adding data to Income and Expense Series
for(int i=0;i<x.length;i++){
systolicSeries.add(x[1], systolic[i]);
// diastolicSeries.add(x[i],diastolic[i]);
// pulseSeries.add(x[i],pulse[i]);
}
// Creating a dataset to hold each series
XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
// Adding Income Series to the dataset
dataset.addSeries(systolicSeries);
// Adding Expense Series to dataset
// dataset.addSeries(diastolicSeries);
// Adding Expense Series to dataset
// dataset.addSeries(pulseSeries);
// Creating XYSeriesRenderer to customize incomeSeries
XYSeriesRenderer incomeRenderer = new XYSeriesRenderer();
incomeRenderer.setColor(Color.WHITE);
incomeRenderer.setPointStyle(PointStyle.CIRCLE);
incomeRenderer.setFillPoints(true);

mChartView = ChartFactory.getLineChartView(this, dataset, multiRenderer);
mChartView.setBackgroundColor(Color.BLACK);
linlayChartLogContainer.addView(mChartView);
