Bug 142403 3D line chart, set marker shape to special shape, interactivity can not take effect.
3D line chart, set marker shape to special shape, interactivity can not take effect. Steps: 1.Create a 3D line chart 2.Open chart builder, go to "Format chart" tab, select Value(Y) series, add a interactivity, click "Markers", select the last one 3.Preview Actual Results: 1.Interactivity can not be take effect Expected Results: 1.Interactivity can be take effect correctly.
