Detailed Description

The Thistle::RadialChart class provides a default implementation for radial charts.

The Thistle::RadialChart class considers that each column from the model is a serie of values. The horizontal header contains the name of series. The vertical headers defines the x-axis data.

Member Function Documentation

QPainterPath itemPath ( const QModelIndex &  index ) const

protectedvirtual

Returns the bounding QPainterPath for the given index.

The QPainterPath should be restricted to the bounding rect.

See Also

itemRect().

Reimplemented from AbstractChart.

QRectF itemRect ( const QModelIndex &  index ) const

protectedvirtual

Defines the outer bounds of the item as a rectangle.

All painting must be restricted to inside an item's bounding rect. Although the item's shape can be arbitrary, the bounding rect is always rectangular.

Reimplemented from AbstractItemView.
