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.

Reimplemented from vtkPlot3D.

◆ SafeDownCast()

◆ PrintSelf()

void vtkPlotSurface::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
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 vtkPlot3D.

◆ New()

static vtkPlotSurface * vtkPlotSurface::New ( )
static

◆ Paint()

bool vtkPlotSurface::Paint ( vtkContext2D painter)
overridevirtual

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

Reimplemented from vtkAbstractContextItem.

void vtkPlotSurface::SetInputData ( vtkTable input,
const vtkStdString xName,
const vtkStdString yName,
const vtkStdString zName 
)
overridevirtual

Set the input to the surface plot.

Do not use these versions of SetInputData, as all the parameters beyond the vtkTable are ignored.

Reimplemented from vtkPlot3D.

◆ SetInputData() [3/4]

void vtkPlotSurface::SetInputData ( vtkTable input,
const vtkStdString xName,
const vtkStdString yName,
const vtkStdString zName,

void vtkPlotSurface::SetYRange ( float  min,
float  max 
)

Set the range of the input data for the Y dimension.

By default it is (1, NumberOfRows). Calling this method after SetInputData() results in recomputation of the plot's data. Therefore, it is more efficient to call it before SetInputData() when possible.
