Hmm...
I did a quick run through the J plot lab until I got to a pd example,
and then I tried out my variation on your script, and it worked fine.
So I exited J (j903) restarted it, and ran the script as my first
action, and this caused J to crash.
So I expect something is not being initialized

After setting plot options as:
polpopts=: 'aspect 1'; 'polar 1'; 'frame 0'; 'axes 1 1'; 'labels 0 0';
'tics 0 0'; 'grids 0 0'
I try to place a notation on the plot:
pd 'text 50x 100x G#'
pd 'show'
|length error: canvas_text
| res=.tolist(.0),each<');'
|canvas_text[11]
