Hi Alexander, I made the test with the line. It works :-) Do you know why it's not implemented in area type?
I was also thinking to create my own type based on the area type but without the vertical line from the point to YMin (to draw the polygon without the border) but without this event it's not very interesting for me. Thanks for the job Alexander.
