is it that maybe point1 and point2 are swapped wrt the linewidget case?

  sliderRep->SetPoint1InWorldCoordinates(x+0.5, y, z);
  sliderRep->SetPoint2InWorldCoordinates(0,0,0);
//...
  auto sliderWidgetX = createSliderWidget(30, renderWindowInteractor,  1, 0, 0);
  auto sliderWidgetY = createSliderWidget(30, renderWindowInteractor,  0, 1, 0);
  auto sliderWidgetZ = createSliderWidget(30, renderWindowInteractor,  0, 0, 1);
