virtual

Turn on/off flag to control whether scalar data is used to color objects.

◆ GetScalarVisibility()

virtual bool vtkPlotBar::GetScalarVisibility ( )
virtual

virtual void vtkPlotBar::ScalarVisibilityOn ( )
virtual

◆ ScalarVisibilityOff()

virtual void vtkPlotBar::ScalarVisibilityOff ( )

virtual void vtkPlotBar::SetEnableOpacityMapping ( bool  )
virtual

Enable/disable mapping of the opacity values.

Default is set to true.

virtual void vtkPlotBar::EnableOpacityMappingOn ( )
virtual

◆ EnableOpacityMappingOff()

virtual void vtkPlotBar::EnableOpacityMappingOff ( )
virtual

◆ 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.

◆ SelectColorArray() [2/2]

void vtkPlotBar::SelectColorArray ( const vtkStdString arrayName)

◆ GetColorArrayName()

vtkStdString vtkPlotBar::GetColorArrayName ( )

Get the array name to color by.

◆ GetLabels()

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]

virtual vtkIdType vtkPlotBar::GetNearestPoint ( const vtkVector2f point,
const vtkVector2f ,
vtkVector2f location,
vtkIdType segmentId 
)
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.
