Stores the settings for rendering of all diagrams for a layer.
Evaluates and returns the diagram settings relating to a diagram for a specific feature.
Map canvas is a class for displaying all GIS data types on a canvas.
Base class for any widget that can be shown as a inline panel.
Model for sub diagrams in a stacked diagram view.
QList< QgsDiagramRenderer * > mRenderers
Represents a vector layer which manages a vector based data sets.
