Detailed Description

Base class for all datasets (XYDatasets, XYZDatasets, CategoryDatasets, OHLCDatasets, etc).

Member Function Documentation

virtual bool Dataset::AcceptRenderer ( Renderer *  r )

protectedpure virtual

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

Implemented in OHLCDataset, XYDataset, and CategoryDataset.

void Dataset::AddMarker

(

Marker *

marker

)

Adds marker to plot. Plot takes ownership of marker.

Parameters

marker

marker to be added

void Dataset::BeginUpdate

(

)

Called to begin dataset update. Each call must have corresponding EndUpdate call. Increment dataset update counter.

void Dataset::DatasetChanged ( )

protected

Called to indicate, that dataset is changed. For call by derivate classes.

Here is the caller graph for this function:

void Dataset::EndUpdate

(

)

Called to end dataset update. Decrement dataset update counter, and fires DatasetChanged event when counter equal zero.

virtual size_t Dataset::GetCount ( size_t  serie )

pure virtual

Returns value count in serie specified by index.

Parameters

serie

index

Returns

value count

Implemented in XYDynamicDataset, XYSimpleDataset, GanttDataset, OHLCDataset, CategoryDataset, Polynom, VectorDataset, MovingAverage, SineFunction, JulianTimeSeriesDataset, and TimeSeriesDataset.

Here is the caller graph for this function:

Marker * Dataset::GetMarker

(

size_t

index

)

Returns marker at specified index.

Parameters

index

index of marker

Returns

marker at specified index

size_t Dataset::GetMarkersCount

(

)

Returns marker count.

Returns

marker count

virtual double Dataset::GetMaxValue ( bool  vertical )

pure virtual

Returns maximal value.

Parameters

vertical

for datasets with XY coordinates, specifies direction

Returns

maximal value

Implemented in XYDataset, OHLCDataset, and CategoryDataset.

virtual double Dataset::GetMinValue ( bool  vertical )

pure virtual

Returns minimal value.

Parameters

vertical

for datasets with XY coordinates, specifies direction

Returns

minimal value

Implemented in XYDataset, OHLCDataset, and CategoryDataset.

virtual size_t Dataset::GetSerieCount ( )

pure virtual

Returns serie count in this dataset.

Returns

serie count

Implemented in XYDynamicDataset, CategorySimpleDataset, XYSimpleDataset, OHLCDataset, GanttSimpleDataset, Polynom, SineFunction, VectorDataset, MovingAverage, JulianTimeSeriesDataset, and TimeSeriesDataset.

Here is the caller graph for this function:

virtual wxString Dataset::GetSerieName ( size_t  serie )

pure virtual

Returns serie name.

Parameters

serie

index

Returns

serie name

Implemented in XYDynamicDataset, CategorySimpleDataset, XYSimpleDataset, OHLCDataset, GanttSimpleDataset, Polynom, SineFunction, VectorDataset, MovingAverage, JulianTimeSeriesDataset, and TimeSeriesDataset.

Here is the caller graph for this function:

void Dataset::NeedRedraw ( DrawObject *  obj )

virtual

Called when object is need to be redrawed.

Parameters

obj	object that need to be redrawed

Implements DrawObserver.

Here is the call graph for this function:

void Dataset::SetRenderer

(

Renderer *

renderer

)

Sets renderer for this dataset.

Parameters

renderer

new renderer
