Detailed Description

draws an area plot.

vtkPlotArea is used to render an area plot. An area plot (sometimes called a range plot) renders a filled region between the selected ymin and ymax arrays. To specify the x array and ymin/ymax arrays, use the SetInputArray method with array index as 0, 1, or 2, respectively.

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

void vtkPlotArea::PrintSelf ( ostream &  os,

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkPlot.

void vtkPlotArea::SetColor ( unsigned char  r,
unsigned char  g,
unsigned char  b,
unsigned char  a 
)
overridevirtual

Overridden to set the brush color.

Reimplemented from vtkPlot.

void vtkPlotArea::SetColor ( double  r,
double  g,
double  b 
)
overridevirtual

Overridden to set the brush color.

Reimplemented from vtkPlot.

virtual vtkStdString vtkPlotArea::GetValidPointMaskName ( )
virtual

Get/set the valid point mask array name.

virtual void vtkPlotArea::SetValidPointMaskName ( vtkStdString  )
virtual

Get/set the valid point mask array name.

void vtkPlotArea::Update ( )
overridevirtual

Perform any updates to the item that may be necessary before rendering.

Reimplemented from vtkAbstractContextItem.

void vtkPlotArea::GetBounds ( double  bounds[4])
overridevirtual

Get the bounds for this plot as (Xmin, Xmax, Ymin, Ymax).

Reimplemented from vtkPlot.

void vtkPlotArea::UpdateCache ( )
overridevirtual

Subclasses that build data caches to speed up painting should override this method to update such caches.

This is called on each Paint, hence subclasses must add checks to avoid rebuilding of cache, unless necessary.

Reimplemented from vtkPlot.

bool vtkPlotArea::Paint ( vtkContext2D painter)
overridevirtual

Paint event for the XY plot, called whenever the chart needs to be drawn.

Reimplemented from vtkAbstractContextItem.

bool vtkPlotArea::PaintLegend ( vtkContext2D painter,
const vtkRectf rect,
int  legendIndex 
)
overridevirtual

Paint legend event for the plot, called whenever the legend needs the plot items symbol/mark/line drawn.

A rect is supplied with the lower left corner of the rect (elements 0 and 1) and with width x height (elements 2 and 3). The plot can choose how to fill the space supplied. The index is used by Plots that return more than one label.

Reimplemented from vtkPlot.

vtkIdType vtkPlotArea::GetNearestPoint ( const vtkVector2f point,
const vtkVector2f tolerance,
vtkVector2f location 
)
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 no point was found.

Reimplemented from vtkPlot.

vtkStdString vtkPlotArea::GetTooltipLabel ( const vtkVector2d plotPos,
vtkIdType  seriesIndex,
vtkIdType  segmentIndex 
)
overridevirtual

Generate and return the tooltip label string for this plot The segmentIndex parameter is ignored, except for vtkPlotBar.
