Detailed Description
Abstract base class for MVC-based charts.
This is an abstract class and should not be used directly.
As an abstract base for MVC-based charts, this class manages the model setModel() and provides virtual methods that listen to model changes. In addition, it gives access to generic chart properties such as the title setTitle() and title font setTitleFont(), the chart palette setPalette(), plot area padding setPlotAreaPadding(), and the background fill color setBackground().
CSS
Styling through CSS is not applicable.

Member Function Documentation
◆ background()
| const WBrush& Wt::Chart::WAbstractChart::background | ( | ) | const |
Returns the background of the chart.
- See also
- setBackground(const WBrush&)
◆ isAutoLayoutEnabled()
| bool Wt::Chart::WAbstractChart::isAutoLayoutEnabled | ( | ) | const |
Returns whether chart layout is computed automatically.
- See also
- setAutoLayoutEnabled()
◆ itemModel()
| std::shared_ptr< WAbstractItemModel > Wt::Chart::WAbstractChart::itemModel | ( | ) | const |
Returns the model.
If a model was set using setModel(const std::shared_ptr<WAbstractItemModel>&), then this model will be returned by this call.
◆ model()
| std::shared_ptr<WAbstractChartModel> Wt::Chart::WAbstractChart::model | ( | ) | const |
Returns the model.
◆ paint()
|
pure virtual |
Paint the chart in a rectangle of the given painter.
Paints the chart inside the painter, in the area indicated by rectangle. When rectangle is a null rectangle, the entire painter window is used.
Implemented in Wt::Chart::WPieChart, and Wt::Chart::WCartesianChart.
◆ palette()
| std::shared_ptr<WChartPalette> Wt::Chart::WAbstractChart::palette | ( | ) | const |
Returns the palette for the chart.
- See also
- setPalette(WChartPalette *palette)
◆ plotAreaPadding()
| int Wt::Chart::WAbstractChart::plotAreaPadding | ( | Side | side | ) | const |
Returns the internal margin for the main plot area.
This is either the paddings set through setPlotAreaPadding() or computed using setAutoLayoutEnabled()
◆ setAutoLayoutEnabled()
| void Wt::Chart::WAbstractChart::setAutoLayoutEnabled | ( | bool | enabled = true | ) |
Configures the chart layout to be automatic.
This configures the plot area so that the space around it is suited for the text that is rendered (axis labels and text, the title, and legend).
The default value is false, and the chart layout is set manually using values set in setPlotAreaPadding().
◆ setBackground()
| void Wt::Chart::WAbstractChart::setBackground | ( | const WBrush & | background | ) |
Sets a background for the chart.
Set the background color for the main plot area.
The default is a completely transparent background.
- See also
- background()
◆ setModel() [1/2]
| void Wt::Chart::WAbstractChart::setModel | ( | const std::shared_ptr< WAbstractChartModel > & | model | ) |
Sets the model.
The model is used by the chart to get its data.
The default model is a nullptr.
- Note
- Setting a new model on a WCartesianChart causes the WCartesianChart::XSeriesColumn() and all series to be cleared
- See also
- model()
◆ setModel() [2/2]
| void Wt::Chart::WAbstractChart::setModel | ( | const std::shared_ptr< WAbstractItemModel > & | model | ) |
Sets the model.
The model is used by the chart to get its data.
The default model is nullptr.
This creates an internal proxy model that presents the WAbstractItemModel as a WAbstractChartModel. Use setModel(const std::shared_ptr<WAbstractChartModel>&) directly for highest performance (avoiding the overhead of any for numeric data).
- Note
- Setting a new model on a WCartesianChart causes the WCartesianChart::XSeriesColumn() and all series to be cleared
- See also
- model()
◆ setPalette()
| void Wt::Chart::WAbstractChart::setPalette | ( | const std::shared_ptr< WChartPalette > & | palette | ) |
Set a palette for the chart.
A palette is used to provide the style information to render the chart series.
The default palette is dependent on the chart type.
- See also
- palette()
◆ setPlotAreaPadding()
Set an internal margin for the main plot area.
This configures the area (in pixels) around the plot area that is available for axes, labels, and titles.
The default is dependent on the chart type.
Alternatively, you can configure the chart layout to be computed automatically using setAutoLayoutEnabled().
- See also
- setAutoLayoutEnabled()
◆ setTitle()
| void Wt::Chart::WAbstractChart::setTitle | ( | const WString & | title | ) |
Set a chart title.
The title is displayed on top of the chart, using the titleFont().
The default title is an empty title ("").
- See also
- title()
◆ setTitleFont()
| void Wt::Chart::WAbstractChart::setTitleFont | ( | const WFont & | titleFont | ) |
Set the font for the chart title.
Changes the font for the chart title.
The default title font is a 15 point Sans Serif font.
- See also
- titleFont(), setTitle(const WString&)
◆ title()
◆ titleFont()
| const WFont& Wt::Chart::WAbstractChart::titleFont | ( | ) | const |
Returns the font for the chart title.
- See also
- setTitleFont(const WFont&)
