For the mouse controls, see Q3DInputHandler documentation, and for the touch controls, + see QTouch3DInputHandler documentation. - \section1 Highlighting data + \note In the technology preview version, default input handlers cannot be replaced or even accessed + via public API. This feature is planned for the final release. - TODO + \section1 Data selection modes + + All visualization types support selecting single data item - a bar, a scatter item, or a surface + vertex - using mouse, touch, and programmatically via the graph APIs. 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. This makes it easier to see the actual values of + single row or column. + + Bar graph additionally supports simply highlighting the whole row and/or column of the selected bar + without opening the slice view. */ |
