I have a bar chart where I've substituted an arrow shape for the bar.
(I did this by selecting an copying an auto shape to my chart, copying
it to the clipboard, selecting all bars in the chart and selecting
paste.)

This looks great on the screen and prints fine in black and white but
when I print in color the arrows become full bars. I thought it might
be my color printer driver but if I print in color to Adobe PDF it
shows full bars instead of the arrows.

Any ideas on what would cause this?

Thanks
