The selected item is highlighted + in the rendered graph, and selecting causes emission of a graph specific signal for this purpose, + e.g. Q3DBars::selectedBarPosChanged(), which the application can handle. + + \note Surface graph doesn't have fully implemented selection API yet, it only supports + selection with mouse and touch in the technology preview version. + + Bar and surface graphs support slice selection modes, where the selected row or column is drawn + in a separate viewport as a pseudo-2D graph.
