Solution
The ActiveX CWGraph-based controls, including the ActiveX 3D Curve Graph, ActiveX 3D Surface Graph, and ActiveX 3D Parametric Graph, are not supported in the 64-bit version of LabVIEW.
To achieve comparable functionality in 64-bit LabVIEW, you can use the 3D Line Graph and 3D Surface Graph front panel objects. These native LabVIEW objects are supported in 64-bit environments and provide the same visualization capabilities as the mentioned ActiveX controls.
