Add an Export Expressions () subnode to these 2D and 3D plots: streamline, streamline surface, radiation pattern, particle trajectories, point trajectories, and ray trajectories. Use the Export Expressions subnode to add expressions for additional quantities to include in plot data export for those plots. For example, you can use it to evaluate and export several expressions on streamlines or to add the frequency as an additional expression for the data export from a far-field plot.

In the table in this section, add the expressions that you want to export in addition the data in the plot (including an optional description). See Expressions and Predefined Quantities for more information about how to add expressions to the table. The values of the added expressions appear in Export columns to the right of the columns with the plot data when exporting that data to a file.
