Exporting a Graph

If you choose to export CSV files to your local host, the files are opened using the spreadsheet software by default. You are advised to open the files in a text editor. If the data contains special characters such as plus signs (+), minus signs (-), equal signs (=), and at signs (@), the data will be parsed into formulas by the software. To ensure system security, pay attention to the following when opening such files:
  1. Do not select Enable Dynamic Data Exchange Server Launch (not recommended).
  2. Do not select Enable or Yes if a dialog box indicating a security issue is displayed.
