Mirroring a graph in POSTFEKO

I have some sim data at 0-180 azimuth plotted in a polar plot. I'd like to mirror this data about AZ 0 to create a symmetric graph from 0-360 azimuth. How can I do this within the POSTFEKO environment?

Thank you in advance!

    Hi @Pete_H ,

    In this case, you could export the data (as .ffe if it's farfield data or as .efe/.hfe if it's nearfield data) and then copy/paste the missing data in a text editor. You could then import the edited .ffe file into POSTFEKO.

    Doing it with lua scripting in POSTFEKO would also work. Unfortunately, I am unable to provide support as I lack the relevant knowledge.

    Best regards,
    Torben

    Hi @Pete_H,

    Could it be you're looking for this?

    Or was the farfield data actually only calculated from 0 to 180 degree? In this case I think you would have to export the data from the graph and manually edit it before re-importing. Or one could do this via lua scripting.

    Thank you Torben. My situation is I only have existing data from 0 to 180.

    Thanks Torben. I have some codes to do what you describe but I was hoping there was a trick within POSTFEKO to save on the "touch labor" of my current task. Thank you for your help.
