Hi,
OK.
Have you tried to run your code without the "pos" parameter?
Based on the help, "pos" should be just *one* parameter. "pos" offers a
finer adjustment of the text. But in your case, the first thing to get is
that the text label is represented at the specified coordinates. Besides
"pos" you can try "adj" which is a parameter that allows you to use two
parameters (between 0 and 1).
Regards,
Carlos Ortega
