◆ SelectColorArray() [1/2]

void vtkPlotBar::SelectColorArray ( vtkIdType arrayNum )

When ScalarMode is set to UsePointFieldData or UseCellFieldData, you can specify which array to use for coloring using these methods.

The lookup table will decide how to convert vectors to colors.

vtkStringArray* vtkPlotBar::GetLabels ( )

overridevirtual

Get the plot labels.

Reimplemented from vtkPlot.

◆ SetGroupName()

virtual void vtkPlotBar::SetGroupName ( const vtkStdString & name )

virtual

Set the group name of the bar chart - can be displayed on the X axis.

◆ GetGroupName()

virtual vtkStdString vtkPlotBar::GetGroupName ( )

virtual

Get the group name of the bar char - can be displayed on the X axis.

◆ GetTooltipLabel()

vtkStdString vtkPlotBar::GetTooltipLabel	(	const vtkVector2d &	plotPos,
		vtkIdType	seriesIndex,
		vtkIdType	segmentIndex
	)

overridevirtual

Generate and return the tooltip label string for this plot The segmentIndex is implemented here.

Reimplemented from vtkPlot.

◆ SelectPoints()

bool vtkPlotBar::SelectPoints	(	const vtkVector2f &	min,
		const vtkVector2f &	max
	)

overridevirtual

Select all points in the specified rectangle.

Reimplemented from vtkPlot.

◆ GetNearestPoint() [1/3]

vtkIdType vtkPlotBar::GetNearestPoint	(	const vtkVector2f &	point,
		const vtkVector2f &	,
		vtkVector2f *	location,
		vtkIdType *	segmentIndex
	)

overridevirtual

Function to query a plot for the nearest point to the specified coordinate.

Returns the index of the data series with which the point is associated or -1. If a vtkIdType* is passed, its referent will be set to index of the bar segment with which a point is associated, or -1.

Reimplemented from vtkPlot.

◆ GetBarsCount()

int vtkPlotBar::GetBarsCount ( )

Get amount of plotted bars.

◆ GetDataBounds()

void vtkPlotBar::GetDataBounds ( double bounds[2] )

Get the data bounds for this mapper as (Xmin,Xmax).

◆ UpdateTableCache()

bool vtkPlotBar::UpdateTableCache ( vtkTable * table )

protected

Update the table cache.

◆ GetNearestPoint() [2/3]

virtual vtkIdType vtkPlot::GetNearestPoint

Function to query a plot for the nearest point to the specified coordinate.

Returns the index of the data series with which the point is associated, or -1 if no point was found.

◆ GetNearestPoint() [3/3]

virtual vtkIdType vtkPlot::GetNearestPoint

Function to query a plot for the nearest point to the specified coordinate.

Returns the index of the data series with which the point is associated, or -1 if no point was found. Deprecated method, uses GetNearestPoint(const vtkVector2f& point, const vtkVector2f& tolerance, vtkVector2f* location, vtkIdType* segmentId); instead.
