How can I copy an entire STATISTICA graph to the Clipboard?
Ensure that the window containing the graph to be copied is active, then press CTRL+C or click the 
toolbar button.
STATISTICA Graphs can be pasted and linked or embedded in other application documents (e.g., word processor documents or spreadsheets) following standard OLE conventions. If STATISTICA Graphs are pasted to OLE-compatible applications, the graphs maintain their relation to STATISTICA and thus can be interactively edited from within the other application, or updated when the STATISTICA Graphs change.
If the STATISTICA Graph copied to the Clipboard has been saved (to a *.stg file), you can link it in other application documents (or STATISTICA's own) by selecting Paste Link from the Edit menu (or Paste Special).
