|
36 | 36 | \brief The QDateTimeAxis class is used for manipulating chart's axis. |
|
37 | 37 | \mainclass |
|
38 | 38 | |
|
39 | 39 | The labels can be configured by setting an appropriate DateTime format. |
|
40 | 40 | QDateTimeAxis works correctly with dates from 4714 BCE to 287396 CE. |
|
41 | 41 | There are also other limitiation related to QDateTime. Please refer to QDateTime documentation. |
|
42 | 42 | QDateTimeAxis can be setup to show axis line with tick marks, grid lines and shades. |
|
43 | 43 | |
|
44 | 44 | Note: QDateTimeAxis is disabled on ARM architecture. |
|

|
47 | 47 | |
|
48 | 48 | QDateTimeAxis can be used with any QXYSeries. |
|
49 | 49 | To add a data point to the series QDateTime::toMSecsSinceEpoch() is used. |
|
50 | 50 | \code |
|
51 | 51 | QLineSeries *series = new QLineSeries; |
|
52 | 52 | |
|
53 | 53 | QDateTime xValue; |
|
54 | 54 | xValue.setDate(QDate(2012, 1 , 18)); |
|
55 | 55 | xValue.setTime(QTime(9, 34)); |
|
56 | 56 | qreal yValue = 12; |
|
57 | 57 | series->append(xValue.toMSecsSinceEpoch(), yValue); |
|
58 | 58 | |
|
59 | 59 | xValue.setDate(QDate(2013, 5 , 11)); |
|
60 | 60 | xValue.setTime(QTime(11, 14)); |
|
61 | 61 | qreal yValue = 22; |
|
62 | 62 | series->append(xValue.toMSecsSinceEpoch(), yValue); |
|
63 | 63 | \endcode |
|
64 | 64 | |
|
65 | 65 | Adding the series to the chart and setting up the QDateTimeAxis. |
|
66 | 66 | \code |
|
67 | 67 | QChartView *chartView = new QChartView; |
|
68 | 68 | chartView->chart()->addSeries(series); |
|
69 | 69 | |
|

|
71 | 71 | QDateTimeAxis *axisX = new QDateTimeAxis; |
|
72 | 72 | axisX->setFormat("dd-MM-yyyy h:mm"); |
|
73 | 73 | chartView->chart()->setAxisX(axisX, series); |
