How To Create a 3-D Surface Graph in Visual FoxPro

Summary

The 3-D Surface graph is not available as one of the graph types in the Graph Wizard. However, you can select the default graph from within the Graph Wizard, and then change the graph type to the 3-D Surface graph once in Microsoft Graph. Or you can use OLE automation. This article shows by example how to do it.
