having problems in a bubble chart...  i can add bubble, square, and round but not x, triangle_(up or down) or romb.

this works:
               chart.bullet = "bubble";

this doesn't work:
               chart.bullet = "romb";

this doesn't work either:
               chart.bullet = "x";

presumably all of these should work:
bubble /square / round / square_outlined / round_outlined / square_outline / round_outline / romb / triangle_up / triangle_down / x / filename.swf


i'd love to have the "x" symbol. 

any suggestions?
