Question

我正在开发一个我需要实现线图的应用程序。

因为我使用Achart引擎绘制折线图，但我想使用一些样本坐标绘制垂直线，但我没能实现它。但是我可以绘制水平线，但不能绘制垂直直线。

 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);
                    incomeRenderer.setLineWidth(2);
                    incomeRenderer.setDisplayChartValues(true);

                /*    // Creating XYSeriesRenderer to customize expenseSeries
                    XYSeriesRenderer expenseRenderer = new XYSeriesRenderer();

                    XYMultipleSeriesRenderer multiRenderer = new XYMultipleSeriesRenderer();

                        multiRenderer.addXTextLabel(i+1, mMonth[i]);
                    }

                    // Adding incomeRenderer and expenseRenderer to multipleRenderer
                    // Note: The order of adding dataseries to dataset and renderers to multipleRenderer
                    // should be same
                    multiRenderer.addSeriesRenderer(incomeRenderer);
                  //  multiRenderer.addSeriesRenderer(expenseRenderer);
                  //  multiRenderer.addSeriesRenderer(pulseRenderer);

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

                    linlayChartLogContainer.addView(mChartView);

                }
            catch (Exception e)

您是否在AchartEngine中尝试过Bar-Chart？它可以绘制垂直线

使用Achartengine绘制垂直折线图
