System templates are stored in the Origin software folder. By default, it is these templates that are called by the Plot menu commands and various graphing toolbar buttons. If you customize a system template and save the template with the same name to your User Files Folder (UFF) (you are not allowed to overwrite the system templates in your Origin software folder), the template becomes your new default template for this plot type. Your customized template then becomes the template associated with the Plot menu commands and graphing toolbar buttons.
Use the System Templates tool to view your system graph templates and plot your Origin worksheet or Excel workbook data to a system template.
To open the System Templates tool, make sure the active window is a workbook or matrixbook and choose Plot: System Templates.
