HFSS - is there a way to display more helpful information on "markers" on graphs?

If I select a result curve is HFSS (e.g. |S11| vs frequency), then I can add markers for the values of best return loss for example. HFSS finds the minium, and puts a marker "m1". A table is created which is 4 columns wide, having nothing in the 4th column.

|Marker| |X| |Y| black column|

Is there any way to put a note in that blank column, or otherwise add some information to the table of markers, so the data is more meaningful. For example, could I change the column titled "X" to be "f (GHz)" for example?

A table with values of m, X and Y is not easy to look at and understand - especially if you want to show the results to someone else. You need to explain the markers, rather than it be obvious to them just by looking at the table.

If you can't do it in HFSS, for a non-ideal solution you could print the graph in a PDF and then edit the PDF for example with Inkscape.

I don't think you need to scratch your head so much for this simple issue. Once you done all the marking, take a screenshot using this software called 'lightshot' (free to download - Search in Google). After that copy the screenshot in microsoft paint and do the necessary editing.

It's simple and fast. After all, it's easier to post images in your report.

Yes you could do a screen shot, but then the quality is not so good. With the PDF (or other vector formats) you'll get a much better quality, especially when you resize the image. And you can edit the text (what you can't in the case of a screen shot). Thus, for a fast but not so high quality edit a screen shot is good, but if you want to publish your results you should use vector graphics.
