QT CHARVIEW EXAMPLE SERIES
The QPercentBarSeries class and PercentBarSeries QML type present a series of categorized data as a percentage of each category. The corresponding horizontal class and type are QHorizontalStackedBarSeries and HorizontalStackedBarSeries, respectively. The QStackedBarSeries class and the StackedBarSeries type present a series of data as vertically stacked bars, with one bar per category. Similarly, the QHorizontalBarSeries class and the HorizontalBarSeries QML type present data as horizontal bars. The QBarSeries class and the BarSeries QML type present data as vertical bars grouped by category. The series type determines how the data is presented. The QAbstractBarSeries class is an abstract parent class for all bar series classes, and the AbstractBarSeries type is the parent type of bar series types. The QBarSet class and the BarSet QML type represent one set of bars in a bar chart. Bar ChartsĪ bar chart presents data as horizontal or vertical bars that are grouped by category. However, you can use QLineSeries or LineSeries as both boundaries.Ī scatter chart is implemented by using the QScatterSeries class or the ScatterSeries QML type.įor more information, see AreaChart Example, ScatterChart Example, and Scatter Interactions Example. By default, the x-axis is used as one boundary and QLineSeries or LineSeries as the other. Area and Scatter ChartsĪrea charts present data as an area bound by two lines, whereas scatter charts present data as a collection of points.Īn area chart is implemented by using the QAreaSeries class or the AreaSeries QML type. For an example of combining a line chart with a bar chart and using a common axis for both, see Line and BarChart Example. The spline is drawn by using QPainterPath.Ī line chart is implemented by using the QLineSeries class or the LineSeries QML type.Ī spline chart is implemented by using the QSplineSeries class that inherits QLineSeries or the SplineSeries type that inherits LineSeries.įor more information, see LineChart Example, SplineChart Example, and Dynamic Spline Example. In a line chart, the data points are connected by straight lines, whereas in a spline chart they are connected by a spline. Line and spline charts present data as a series of data points connected by lines.
You can combine different types of series in one chart. ChartThemeBrownSand antialiasing: true PieSeries Charts are created by using an instance of a series class and adding it to a QChart or ChartView instance. The Qt Charts module provides the following chart types:Įach chart type is represented by an QAbstractSeries derived class or AbstractSeries derived type in QML. Model mappers can be either horizontal or vertical. Model mappers enable using a data model derived from the QAbstractItemModel class as a data source for a chart.
The look and feel of charts can be customized by using themes, modifying colors and properties, hiding chart components, or animating charts.
Some chart components can also be presented as polar charts by using the the QPolarChart class that is a specialization of the QChart class or the PolarChartView QML type that is a specialization of the ChartView type. In QML, charts are displayed using the ChartView type. A simpler solution is to display a chart in a layout by using the convenience class QChartView instead of QChart. QChart is a QGraphicsWidget that can be shown in a QGraphicsScene. The QChart class manages the graphical representation of different types of series and other chart related objects, such as legend and axes. The chart components can be used as QWidget or QGraphicsWidget objects or QML types. Qt Charts uses the Graphics View Framework for ease of integration. Qt Charts enables creating stylish, interactive, data centric user interfaces.
