void Update() override
Perform any updates to the item that may be necessary before rendering.
bool UpdateLayout(vtkContext2D *painter) override
Update the layout of the chart, this may require the vtkContext2D in order to get font metrics etc.
vtkSmartPointer< vtkPlotHistogram2D > Histogram
vtkPlot * GetPlot(vtkIdType index) override
Get the plot at the specified index, returns null if the index is invalid.
bool Hit(const vtkContextMouseEvent &mouse) override
Return true if the supplied x, y coordinate is inside the item.
virtual void SetInputData(vtkImageData *data, vtkIdType z=0)
virtual void SetTransferFunction(vtkScalarsToColors *function)
static vtkChartHistogram2D * New()
Creates a 2D histogram chart.
