Detailed Description

Base class for XY datasets.

Member Function Documentation

bool XYDataset::AcceptRenderer ( Renderer *  r )

protectedvirtual

Checks whether renderer is acceptable by this dataset. TODO: this method must be removed, because acceptable renderer type depends on plot type.

Implements Dataset.

Reimplemented in CategoryDataset.

double XYDataset::GetMaxValue ( bool  vertical )

virtual

Returns maximal value.

Parameters

vertical

for datasets with XY coordinates, specifies direction

Returns

maximal value

Implements Dataset.

Reimplemented in CategoryDataset.
