Exporting a Graph (1.0.5)

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.
