30 30 \class QDateTimeAxis
31 31 \brief The QDateTimeAxis class is used for manipulating chart's axis.
32 32 \mainclass
33 33
34 34 The labels can be configured by setting an appropriate DateTime format.
35 35 QDateTimeAxis works correctly with dates from 4714 BCE to 287396 CE
36 36 There are also other limitiation related to QDateTime . Please refer to QDateTime documentation.
37 37 QDateTimeAxis can be setup to show axis line with tick marks, grid lines and shades.
38 38
39 39 NOTE: QDateTimeAxis is disabled on ARM platform at the present time.
40 40
41 41 \image api_datatime_axis.png
42 42
43 43 QDateTimeAxis can be used with QLineSeries, QSplineSeries or QScatterSeries.
44 44 To add a data point to the series QDateTime::toMSecsSinceEpoch() is used.
45 45 \code
46 46 QLineSeries *series = new QLineSeries;
47 47
48 48 QDateTime xValue;
49 49 xValue.setDate(QDate(2012, 1 , 18));
50 50 xValue.setTime(QTime(9, 34));
51 51 qreal yValue = 12;
52 52 series->append(xValue.toMSecsSinceEpoch(), yValue);
53 53
54 54 xValue.setDate(QDate(2013, 5 , 11));
55 55 xValue.setTime(QTime(11, 14));
56 56 qreal yValue = 22;
57 57 series->append(xValue.toMSecsSinceEpoch(), yValue);
58 58 \endcode
59 59
60 60 Adding the series to the chart and setting up the QDateTimeAxis.
61 61 \code
62 62 QChartView *chartView = new QChartView;
63 63 chartView->chart()->addSeries(series);
64 64
65 65 // ...
66 66 QDateTimeAxis *axisX = new QDateTimeAxis;
