A box plot series acts as a container for box-and-whiskers items. Items from multiple series are grouped into categories according to their index value.
BarCategoryAxis class is used to add the categories to the chart's axis. Category labels have to be unique. If the same category label is defined for several box-and-whiskers items, only the first one is drawn.
The following QML code snippet shows how to create a simple box-and-whiskers chart:
import QtQuick 2.0 import QtCharts 2.0 ChartView { title: "Box Plot series" width: 400 height: 300 theme: ChartView.ChartThemeBrownSand legend.alignment: Qt.AlignBottom BoxPlotSeries { id: plotSeries name: "Income" BoxSet { label: "Jan"; values: [3, 4, 5.1, 6.2, 8.5] } BoxSet { label: "Feb"; values: [5, 6, 7.5, 8.6, 11.8] } BoxSet { label: "Mar"; values: [3.2, 5, 5.7, 8, 9.2] } BoxSet { label: "Apr"; values: [3.8, 5, 6.4, 7, 8] } BoxSet { label: "May"; values: [4, 5, 5.2, 6, 7] } } }

axisX : AbstractAxis |
The x-axis used for the series. If you leave both axisX and axisXTop undefined, a BarCategoryAxis is created for the series.
另请参阅 axisXTop .
axisXTop : AbstractAxis |
The x-axis used for the series, drawn on top of the chart view.
注意: You can only provide either axisX or axisXTop, but not both.
axisY : AbstractAxis |
The y-axis used for the series. If you leave both axisY and axisYRight undefined, a ValueAxis is created for the series.
另请参阅 axisYRight .
axisYRight : AbstractAxis |
The y-axis used for the series, drawn to the right on the chart view.
注意: You can only provide either axisY or axisYRight, but not both.
