00044     if (obj instanceof CanvasHxHistogram3d) {
00045         _hist = (CanvasHxHistogram3d) obj;
00046         _elevField.setText(java.lang.String.valueOf(_hist.getElevation()));
00047         _alphaField.setText(java.lang.String.valueOf(_hist.getAlpha()));
00048         _thresField.setText(java.lang.String.valueOf(_hist.getThreshold()));
00049         return _visualizer.addObject(obj);
00050     }
