Hi John,
thanks. I actually found two more methods that I find even more convenient. Maybe this is of interest for other people too:
1) Add background model. Open the "system" graph control (4th icon from the right, looks like a turquoise tissue box) in the plot graph data window. There I have the option of exporting an image as WMF, BMP or JPEG to a selected location. Voila!
2) In the "Background model" window, click print. It will print the graph into a pdf document. Open in Acrobat, copy and paste into the document.
Not sure if this is the best place but as it is related to WDS scans and documentation, another question:
When I plot several wavescans together in one graph, they all show with the same color. I found how to change the color, weight, pattern etc but it will always apply them to the entire set of line. Is there a way to select each line individually and change its color etc.?
