Can I import a graph from another graphics program to Prism?

You can copy and paste a picture from another application to include on a Prism graph or layout.

If you copy and paste (or export, then import) a graph made with another program, you'll bring in only a picture. You won't be able to modify the graph within Prism, and Prism will have no access to the data.

When that is a problem, consider importing data from the other programs, using copy-and-paste or by exporting/importing a text file, and allowing Prism to make a new graph. But make sure the pasted data fits the Prism data table format that will lead to the graph you want. Check here to learn more about data entry in Prism.
