示例1: refreshData

private void refreshData() {
    LineData data = lineChart.getData();
    if (data != null) {
        LineDataSet set = (LineDataSet) data.getDataSetByIndex(0);
        if (set == null) {
            set = createSet();
            data.addDataSet(set);
        }

        if (set.getEntryCount() == timeframe) {
            data.removeXValue(0);
            set.removeEntry(0);
            for (Entry entry : set.getYVals()) {
                entry.setXIndex(entry.getXIndex() - 1);
            }
        }

        // add x-value
        Date date = new Date();
        Calendar calendar = GregorianCalendar.getInstance();
        calendar.setTime(date);
        int inthours = calendar.get(Calendar.HOUR_OF_DAY);
        int intminute = calendar.get(Calendar.MINUTE);
        String hourString = String.format("%02d:", inthours);
        String minuteString = String.format("%02d", intminute);
        XAxisTimeValue.add(hourString + minuteString);
        data.addXValue(XAxisTimeValue.get(data.getXValCount()));

        // choose a dataSet
        //RealmResults<BGdata> results = realm.allObjects(BGdata.class);
        //RealmLineDataSet(RealmResults<T> results, "calculated_value")
        //RealmLineDataSet<BGdata> dataSet = new RealmLineDataSet<BGdata>(results, "calculated_value");
        //RealmLineData dataset = new RealmLineData(results, "calculated_value", (List<ILineDataSet>) data);

        //lineChart.setData(dataset);


        data.addEntry(new Entry((float) calculated_value, set.getEntryCount()), 0);
        lineChart.notifyDataSetChanged();

        lineChart.setVisibleYRangeMaximum((float) calculated_value, YAxis.AxisDependency.LEFT);
        // this automatically refreshes the chart (calls invalidate())
        lineChart.moveViewTo(data.getXValCount(), (float) calculated_value, YAxis.AxisDependency.LEFT);
    }
