Choose Select Column menu item to specify column from current folder or current project. This column will be any column other than the current X or Y data column, regardless of column designation. With this context menu, you can change the X or Y data of the current plot to be another column in the current project. Choose Yes and click OK so that the updated plot will be auto-rescaled.
See this tutorial on plotting from user-defined graph templates to learn how to save and use both standard and cloneable templates. These templates are designed for "smart plotting", meaning you can clone a graph with a complicated layer hierarchy or with source data that cannot be specified by simple selection. Starting with Origin 2016, a more powerful "cloneable" template has been added.
The Plot Setup dialog offers more flexibility in creating plots, such as plotting data from multiple books or sheets. Creating a graph in Origin is as simple as selecting the desired data and then selecting a template from a menu or from the graphing toolbars. You can create and modify templates by your own and add to the collection.
