There are a few things you need to know before starting to copy a graph from Excel to Illustrator. First, the graph must be in a format that Illustrator can understand. This means that it must be in a Venn diagram or other similar shape. Second, the axes must be labeled correctly and the data must be in columns and rows. Finally, the colors should be consistent between both programs. To begin, open Illustrator and create a new document by clicking on the New button on the left side of the screen. In this new document, select Venn diagrams as your source material. Next, click on the Edit button on the top left of Illustrator and select Copy from the context menu. Once you have copied the graph, click on OK to close Illustrator and return to Excel. Now that you have copied your graph into Illustrator, it is time to start editing it! First, make sure that all of your axes are labeled correctly and that all of your data is in columns and rows. Next, change all of your colors so that they match those used in your original graph. Finally, make any necessary adjustments to ensure that everything looks correct before saving your work for later use!
