如何打破 graphview 数据点以仅获取 Y 轴的值？

Question

我想打破数据点以仅获取 Y 轴的值。现在我的代码运行时得到的结果是：

舒张压读数：[25.0/89.0] mmHg

但是我想将其显示为：

舒张压读数：89.0 mmHg

series_D.setOnDataPointTapListener(new OnDataPointTapListener() {
        @Override
        public void onTap(Series series, DataPointInterface dataPoint) {
            Toast.makeText(Rsults.this, "Diastolic Reading : "+ dataPoint +" mmHg", Toast.LENGTH_SHORT).show();
        }
    });

Answer 1

在 Selvin 的帮助下，代码现在可以正常工作了

series_b.setOnDataPointTapListener(new OnDataPointTapListener() {
        @Override
        public void onTap(Series series, DataPointInterface dataPoint) {
           Double x = dataPoint.getY();
            Toast.makeText(Rsults.this, "Systolic Reading : "+ x +" mmHg", Toast.LENGTH_SHORT).show();
        }
    });
