The data is drawn as a series of vertical bars grouped by category, with one bar per category from each bar set added to the series.
The following QML code snippet shows how to create a simple grouped bar chart:
ChartView { title: "Bar series" anchors.fill: parent legend.alignment: Qt.AlignBottom antialiasing: true BarSeries { id: mySeries axisX: BarCategoryAxis { categories: ["2007", "2008", "2009", "2010", "2011", "2012" ] } BarSet { label: "Bob"; values: [2, 2, 3, 4, 5, 6] } BarSet { label: "Susan"; values: [5, 1, 2, 4, 1, 7] } BarSet { label: "James"; values: [3, 5, 8, 13, 5, 8] } } }
