How to plot rotated cross and color them with cpt palette

Hi,
I tried to remove any comment lines but the problem remain the same.
However I did some other test and I found two more indication:

  • the line “$1 O” it seem option not recognized by pygmt, if I delete this line the script works to the end (even if symbols are not rotated).
  • If in my def file I substitute the “+” symbols with other standard one (as circle or square) the script works, while if I use the “+” symbols I get the error

plot [ERROR]: Unrecognized symbol code (43 = ‘+’) passed to gmt_draw_custom_symbol

I don’t know if these two more indication could be useful but at the moment the problem remain.
