Member Function Documentation

◆ calculateGrid()

DataDimensionsList TernaryGrid::calculateGrid ( const DataDimensionsList & rawDataDimensions ) const

overridevirtual

Calculates the grid start/end/step width values.

Gets the raw data dimensions - e.g. the data model's boundaries, together with their isCalculated flags.

Returns the calculated start/end values for the grid, and their respective step widths. If at least one of the step widths is Zero, all dimensions of the returned list are considered invalid!

Note: This function needs to be implemented by all derived classes, like CartesianGrid, PolarGrid, ...

Implements KDChart::AbstractGrid.

Definition at line 184 of file KDChartTernaryGrid.cpp.

◆ drawGrid()

void TernaryGrid::drawGrid ( PaintContext * context )

overridevirtual

Doing the actual drawing.

Every derived class must implement this.

Note: When implementing drawGrid(): Before you start drawing, make sure to call updateData(), to get the data boundaries recalculated. For an example, see the implementation of CartesianGrid:drawGrid().

Implements KDChart::AbstractGrid.

◆ requiredMargins()

QPair< QSizeF, QSizeF > TernaryGrid::requiredMargins ( ) const

Returns two QSizeF objects specifying the dimension of the margins needed between each corner of the diagram and the border of the drawing area. Margins are required because the tick marks are placed outside of the trianges containing rectangle. The margins are returned in diagram coordinates, since the grid does not know about widget coordinates.

◆ tickInfo()

const QVector< TickInfo > & TernaryGrid::tickInfo ( ) const

Return the locations of the grid lines, so that axes can draw axis rulers at the correct positions. This information is valid after the grid has been painted (that is, the axes need to be painted after the grid.
