{
public:
static customMouseInteractorStyle* New();
vtkTypeMacro(customMouseInteractorStyle, vtkInteractorStyleTrackballCamera);

virtual void OnRightButtonDown();

};

vtkStandardNewMacro(customMouseInteractorStyle);

void customMouseInteractorStyle::OnRightButtonDown()
{
vtkInteractorStyleTrackballCamera::OnRightButtonDown();

std::cout << "test";

};

void viewGraph::DrawGraph() {
vtkNew colors;

vtkNew style;
renderWindowInteractor->SetInteractorStyle(style);
}

**Inside my DrawGraph() I have created my xy chart

Thank you in advance.

VtkChart is a subclass of vtkAbstractContextItem which handles its own mouse events. So subclass vtkChart and then override the mouse handling methods directly there, not in the interactor style.
