I made two tries - first, I used gsn_text_ndc, but it appeared too crowded, and it doesnot look good to squeeze those text below the labelbar. Changing paper margin doesnot work in this case.

Xin,

Right now you have four columns of text strings, each with 6 rows. Perhaps you could do 3 columns of text each with 8 rows? Or, you could try moving the second column to the right a little.

Part of the issue may be that the plot is already taking up a good part of the screen. You can make your plot smaller by setting the vpWidthF and vpHeightF resources to values between 0 and 1, and making sure that you *don't* have gsnMaximize set to True. You may also want to set vpYF to some higher value, like 0.9 (you may have to try several values) to move the plot up. This will allow you force more space underneath the plot where you can put extra text.

You can try moving the labelbar closer to the plot by setting pmLabelBarOrthogonalPosF to some small negative number (start with -0.01).

You could also make the labelbar vertical (lbOrientation = "vertical") so the labelbar is on the side of your plot, and thus you'll have even more room at the bottom for text.

If you just want to label the labelbar directly, then move it to the side with res@lbOrientation = "vertical", and then set res@lbLabelStrings to the text strings you want.
