Would it be possible to have a property that specifies the angle with
respect to the series point that marks are drawn at ? It seems that
vertical style series (line, bar) have them positioned above the series
points (or below at 180 degrees by setting the arrow length as negative).
Horizontal series position them to the right at 90 degrees (or left).
Having an angle property (or at least 0,90,180,270 degree options) would
allow more flexibility.
I find their default angle obscures information present in a back image.
Thanks,
Steve
