Member Function Documentation

virtual bool OHLCDataset::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.

virtual size_t OHLCDataset::GetCount ( )

pure virtual

Returns item count.

Returns

item count

Implements DateTimeDataset.

Implemented in OHLCSimpleDataset.

virtual size_t OHLCDataset::GetCount ( size_t  serie )

virtual

Returns value count in serie specified by index.

Parameters

serie

index

Returns

value count

Implements Dataset.

virtual time_t OHLCDataset::GetDate ( size_t  index )

virtual

Returns date/time for specified index.

Parameters

index

index

Returns

date/time for specified index

Implements DateTimeDataset.

virtual OHLCItem* OHLCDataset::GetItem ( size_t  index )

pure virtual

Returns item on index.

Parameters

index

index of item

Implemented in OHLCSimpleDataset.

virtual double OHLCDataset::GetMaxValue ( bool  vertical )

virtual

Returns maximal value.

Parameters

vertical

for datasets with XY coordinates, specifies direction

Returns

maximal value

Implements Dataset.

virtual double OHLCDataset::GetMinValue ( bool  vertical )

virtual

Returns minimal value.

Parameters

vertical

for datasets with XY coordinates, specifies direction

Returns

minimal value

Implements Dataset.

virtual size_t OHLCDataset::GetSerieCount ( )

virtual

Returns serie count in this dataset.

Returns

serie count

Implements Dataset.

virtual wxString OHLCDataset::GetSerieName ( size_t  serie )

virtual

Returns serie name.

Parameters

serie

index

Returns

serie name

Implements Dataset.

void OHLCDataset::SetSerieName ( const wxString &  serieName )

inline

Sets serie name.

OHLC datasets contains only one serie.

Parameters

serieName

new serie name
