Hello,

Is there a quick way to tell Lightning Chart to "Zoom to extents"?

The app allows the user to switch between default perspective view
m_chart.View3D.Camera.SetPredefinedCamera(PredefinedCamera.Default);

: Default View; perspectiveview.jpg (224.24 KiB) Viewed 6341 times

and top 2D view
m_chart.View3D.Camera.SetPredefinedCamera(PredefinedCamera.TopOrthographicZX);

: Default TopOrthographicZX view; orthogonalviewdefault.jpg (162.95 KiB) Viewed 6341 times

what I would like to do is have it zoom to extents on switching, so it looks like this:

To fit the axis ranges to contents of series, you can do that like this:

Code: Select all

 m_chart.BeginUpdate(); 

            m_chart.View3D.SurfaceGridSeries3D[0].IncludeInAutoFit = true;
            PointDouble3D p1, p2;
            m_chart.View3D.ZoomPanOptions.GetAutoFitRange(out p1, out p2);
            m_chart.View3D.XAxisPrimary3D.SetRange(p1.X, p2.X); 
            m_chart.View3D.YAxisPrimary3D.SetRange(p1.Y, p2.Y);
            m_chart.View3D.ZAxisPrimary3D.SetRange(p1.Z, p2.Z);

            m_chart.EndUpdate();

IncludeInAutoFit is per series. With that you pick the series you want to count in the fitting.
